<< Elastic behaviour in the horizontal direction can be described by a tangential coefficient of restitution, which is about 0.5 or 0.6 for a superball but only about 0.2 for a baseball on a rigid surface. White ash, sugar maple, true hickory, yellow birch, red oak, and Japanese ash are the six wood types that can be used in bats in Major League Baseball. When To Know Its Time To Replace Your Baseball Mitt, Customizing Your Baseball Bag: A Guide To Personalizing Your Equipment. In case that didnt quite clear it up for you, lets break this down a bit. the location where maximum energy is transferred to the ball. } /P 17 0 R However, it will also feel heavier when swung. We call the point where a baseball bat has its nodes the sweet spot. Necessary cookies are absolutely essential for the website to function properly. Despite the likelihood of your bat breaking, there are things you can do to prevent it. As Russell explained before, there are two related ideals that we conflate into one sweet spot. The second definition is where the ball comes off the bat fastest. The bounce factor found from these and some additional impacts is shown below. The weight of a bat can be calculated by subtracting the minus number from the length, which in this case is 33 minus -3, equaling 30 ounces. Yes, every ounce makes a difference. It is not easy to find information on the actual rate of spin of a softball in flight, but it is relatively easy to measure, at least at low ball speeds and low spin speeds. There is obviously some elastic behaviour in the vertical direction as well, which is why the ball bounces up off the block. Although playing a game of cricket requires a significant amount of time, it is filled with powerful and fast forces. The physics behind this phenomenon involves the transfer of energy from the bat to the ball. How do you control where to hit a baseball? A ball takes on a different shape as it is hit because the force of the bat pushing against it is multiplied by its mass. According to one study, Brazils free-tailed bats have the fastest flight speeds ever documented by flying at 160 kilometers per hour in flight.

He received his Ph.D. in physics from the University of California, Berkeley, where he conducted research on particle physics and cosmology. 6 0 obj The COR for a collision between the bat and the ball is less than 0.59 when energy is lost to vibrations, but can be greater than 0.59 if the bat has a trampoline effect on the ball. /R [316 74 572 585 ] This force is required to change a 5 1/8th-ounce ball from a speed of 90 mph to a speed of 110 mph, this distorts the baseball to half its original diameter and the bat is compressed one fiftieth of its size.. This equation for acceleration can , Dry ice is the name for carbon dioxide in its solid state. The following three movies show a batter swinging three different bats as fast as possible, filmed at 25 frames/sec. /V 24 0 R An impact at the fundamental node will not excite that mode, but it will excite the second mode. It is almost as easy as walking. To view the purposes they believe they have legitimate interest for, or to object to this data processing use the vendor list link below. Join PopSci+ to read sciences greatest stories. Since its vibrations that hurt your grip, the sweet spot is clearly the point where an impacting ball doesnt cause the bat to vibrate. /F 3 0 R /N 21 0 R This is why it is important that baseball bats are made out of a hard material that can maximize the energy transfer while also reducing the risk of injury to the player. However, the centripetal force does not act along the axis of the bat, but at an angle, as shown by the orange lines. The bat is 84 cm long, and has a mass of 849 gram. The mode shape of a baseball or softball bat is a simple flexing bending shape that has parts that move and parts that don't. Every bat has a point about seven inches in from the tip of the bat that doesn't move, that doesn't vibrate, called a node. The second definition is where the ball comes off the bat fastest. The lines behind the bat, passing through the axis, mark out angles of 5, 10, 15, 20, 25 and 30 degrees. Baseball is based on the principles of Newtons laws of motion. For most bats all of these "sweetspots" are at different locations on the bat, so one is often forced to define the sweetspot as a region, approximately 5-7 inches from the end of the barrel, where the batted-ball speed is the highest and the sensation in the hands if minimized. /P 23 0 R The third law explains what happens to a bat when it strikes a ball. /V 12 0 R It minimizes vibration of the bat and results in the maximum energy delivered to the ball, meaning it travels the farthest. Metal bats, on the other hand, are lighter and more forgiving, but they lack the power of iron bats. If the ball is at rest (when striking a ball off a T ) then. When you hit a stick off center, two things happen: The entire stick wants to move straight backward, and it also wants to rotate around its center. This cookie is set by GDPR Cookie Consent plugin. It is not the actual weight that determines the swing speed but the swing weight (ie the moment of inertia). 3. As discussed earlier, missing the sweet spot can cause vibrations in the bat. The shapes of the force vs time curves are interesting since they tell us how the force on the ball varies with the amount of compression. >> A good power hitters bat is an end-loaded one, which allows the player to hit the ball farther. After completing his degree, George worked as a postdoctoral researcher at CERN, the world's largest particle physics laboratory. These spots are also described in the physics of tennis page. Advertisement cookies are used to provide visitors with relevant ads and marketing campaigns. The horizontal speed at the contact point depends on the rate at which the ball spins, as well as on the horizontal speed of the centre of mass of the ball. /P 14 0 R A high performance bat has a strong trampoline effect and hence a relatively large COR. Near the end of the swing, the force is roughly at right angles to motion of the handle since the centripetal force is very large. /I << James Sherwood has a similar site http://m-5.eng.uml.edu/umlbrc describing test procedures used to certify baseball bats and balls at the University of Massachusetts Lowell. The COR for the impact on the granite block is about 0.59 in the low speed collision here, but can be as low as 0.45 in a 100 mph collision. The bounce was filmed at 300 fps and is played back at 30 fps in slow motion. /V 19 0 R Aluminum tubes are 24 to 35 inches (61 to 89 centimeters) long and 2 to 3 inches (5 to 7.6 centimeters) in diameter for making an aluminum bat. A similar result is obtained when swinging cylindrical rods, as described in a paper that can be downloaded here. << The answer depends on how fast each bat can be swung. Softer and less dense varieties of maple that are more likely to break have been banned by Major League Baseball. According to Newtons second law of motion, the acceleration of an object equals the net force acting on it divided by its mass, or a = F m . Explains r. cross, "the sweet spot of a baseball bat," american journal of physics, 66, 772-779. Step up to the batters box and get warmed up for the physics of baseball bats with this great video from ESPN Sports Science. Both the swinging bat and the pitched ball possess kinetic energy, which is generated by the players who swing the bat and throw the ball. And though the term is almost always used exclusively to talk about baseball, the scientific principles that explain the sweet spot are actually true of tennis rackets, hockey sticks, and cricket bats as well. If you turn the volume up you will hear how the swing speed affects the sound of the swish through the air. When a player has a bad hit and fails to hit the sweet spot, it causes vibrations which can cause the bat to bend or break. This website uses cookies to improve your experience while you navigate through the website. These vibrations travel in waves up and down the length of the object. Functional cookies help to perform certain functionalities like sharing the content of the website on social media platforms, collect feedbacks, and other third-party features. In recent years, an acoustics professor and engineer, Daniel Russell, from Pennsylvania State University helped develop a Kevlar-based vibration damper to help combat the painful sting of missing the sweet spot (only the physical sting, though). Most contact and power hitters use maple bats because the material is the strongest and has very little give, which is why they swing ash bats. /N 13 0 R We can then ask a similar question. It would therefore not be surprising if a softball can be pitched at say 1000 rpm. << A bat that is too light also hampers the development of a solid, level swing. /P 11 0 R >> The tangential COR is defined in the same way as the normal COR, but in terms of the horizontal speed of the ball at the contact point rather than the normal (ie vertical) speed of the contact point. /Length 459 15 0 obj How is this described in Mechanics? /P 17 0 R The sound made by a bat can be described as a "ping". Regardless of age, the weight of the right handers bat is crucial. When you use a heavier bat, the faster you hit the ball, the longer it will travel. hitting a baseball is either painful or frustrating. The size and weight of the bat is a matter of personal preference, but it is important to remember that a bat must be approved by the league in order to be used in official games. Choosing the right wood is essential for the proper performance of baseball bats. At one point, called the node, the waves always cancel each other out. As a result, the fundamental and second vibration modes are both excited with about the same amplitude. /V 15 0 R This cookie is set by GDPR Cookie Consent plugin. This includes both the length of the barreltop part of the batand its diameter The longer the barrel, generally, the larger the sweet spot for hitting the ball The standard diameter is 2 , and big barrel bats, allowed in some leagues, are 2 5/8. The film is shown here, taken at 25 frames/sec. Concentration. The second you swing one, there is a certain romance to it. /P 23 0 R The impact of a bat and a ball is still not properly understood. Specifically, what forces and torques are exerted on the handle, and in what directions do they act? However. Pitching Mechanics.- 6. The cookie is used to store the user consent for the cookies in the category "Performance". Recent Research Highlights. Near the end of the swing, the batter needs to exert a large negative couple on the bat, otherwise the bat will swing around too fast and strike the ball when it is aligned at the wrong angle. For a tennis racquet only the fundamental mode of vibration is excited by the impact since the impact duration, about 5 msec, is too long to excite higher frequency modes of the racquet. The mass moment of inertia (MOI) is a measure of the distribution of mass in the bat. At other impact points, the impact is usually felt as a sting or jarring of the hands and forearm, particularly if the impact occurs at a point well removed from the sweet spot. The spot is close to the centre of percussion (COP) for a freely supported bat, so it was thought at one time that the sweet spot might be associated with the COP. The faster the hit ball travels, the longer it should travel. So grab your bat and lets dive into the science behind the swing! The COR for the impact on the granite block is about 0.59 in the low speed collision here, but can be as low as 0.45 in a 100 mph collision. For those of us not trying to make it to the majors, using a wooden bat is mostly just a reminder that hitting a baseball is either painful or frustrating, depending on whether youve made contact with the ball or not. The softball bat will vibrate mainly because it either hitting or missing the sweet spot. You can tell the bat is too heavy if the player appears to be chopping at the ball. produce and innovate modern day cricket bats. The heavier the bat, the higher the bats bat speed. Just look for ovals going around each other. Baseball bats are most commonly made out of wood, such as maple, ash, or bamboo. 22 0 obj However, it will also feel heavier when swung. Articles may contain affiliate links which enable us to share in the revenue of any purchases made. } Licensed under CC BY-SA 2.0, via Flickr Creative Commons. If the ball is also mounted as a pendulum. A lot has been learned over the years but more experiments need to be done to better understand how the ball bounces and how much spin it acquires when it bounces. << In order to determine how each of the sweet spots influences the "feel" of the bat, measurements were made of the impact forces transmitted to the hands. The technique here can be be used to measure the performance of any bat, at least at low ball speeds. Since the CM traces out a spiral rather than a circular path, the center of the circle moves, as the bat is swung, along the path traced out by the inner circle of black dots. The result was not a super slow softball spin, neither was it particularly fast. In this article, well explore the various components that go into making a baseball bat, as well as how they work together to help a hitter put their best foot forward. endobj It was found, by measuring the frequencies of lots of aluminum tubes (see photo) that the frequency is directly proportional to the wall thickness and inversely proportional to the tube diameter squared. It is critical for any baseball player to know his or her bat weight before purchasing one; you must consider the weight of the bat in order to purchase it. Elastic Properties of Balls.- 9. Where is the center of mass in a baseball bat? One of these sweet spots relates to vibration. But opting out of some of these cookies may affect your browsing experience. First and foremost, we develop a simple but effective theoretical model to give a rough estimate for the sweet spot of the bat. The bat breaks when large amplitude vibrations reach the thin part of the handle. Physicist Daniel A. Russell explains the physics of a baseball swing with a bat. Boxing. The bat was swung through an angle of about 30 degrees to strike the ball. The node sweet spot differs from the center of percussion sweet spot. 18 0 obj Rather, most coaches and others think in terms of wrist torque, which is probably much too small to provide the necessary large couple near the end of the swing The couple must come mainly from the two arms, not the wrists. Why? The experiment can be done at low bat and ball speeds since the essential physics of the problem does not depend on the actual bat and ball speeds. Not hitting the ball with the sweet spot of the bat causes more vibrations, which causes the sting for the batter. /R [52 73 308 791 ] endobj In practice, batters tend to prefer bats that are lighter, rather than more powerful, since lighter bats are easier to swing and make it easier for the batter to connect with the ball. /V 7 0 R >> The ball bounces backward spinning counter-clockwise. Similarly, an impact at the node of the second mode will not excite the second mode but it will excite the fundamental mode. Are you a fan of composite or wood? Also shown for comparison is a bounce off a heavy block of granite so that the COR of the ball can be determined. Good eyesight. This makes the game easier to pick up and more exciting to watch otherwise, every hit would only be a single. Image by Pulkit Sinha Own work. The idea is to mount a bat as a pendulum and strike it with a ball at various spots along the barrel. In theory, this should mean that a homerun hit right on the sweet spot would sound different from an off-target pop fly. Why dies the bat vibrate inside or outside of the sweet spot? But how does a batter do it? Players tend to feel a zing in their hands; often called bat sting. >> If the vibration frequency is less than about 1000 Hz, the end result is that ball comes off the bat at a lower speed than off a wood bat of the same weight and swing weight. >> } << Otherwise, the effective mass of the bat is less than its whole mass. Taking the rotation rate as 3/8 revolution / 0.04 sec gives 9.4 revolutions / sec or 560 rpm. 3. J,g]g+e/h_!_gCtO=0f)$P%cIi8Zdfc5&3j_8$7g. At the major league level, maple bats now account for 75% to 80% of all bats. The same thing happens when swinging a golf club, but it is not a well-known effect. That said, composite and metal bats are still used by younger players who are still developing their skills. /P 8 0 R PbLSZTLEE(8E@'*1mg_*eTnN*;*'V3+gm-EEetX%;Bo$ur2ss*N`.-!.kG_q6GDD' The collision of a bat and a ball can be understood by treating the bat as a heavy ball whose mass depends on the impact point. Basic Physics.- 2. It is not difficult to swing a bat. All of these are needed to hit a baseball at the Major League level. What have you found works for you? The sweet spot of a bat exists because bat vibrations are not excited significantly at that spot. The relevant collision equations are derived in the Physics of Baseball and Softball book (and elsewhere) and are: 1. on: function(evt, cb) { endobj That should sound like more of a thud, because youre not hearing the vibrations inside the wood. /N 16 0 R 2.1. So, for the sake of the integrity of the game and safety, bats have remained wooden. /BitsPerComponent 8 There is enough physics in it to keep a PhD student busy for a few years, but it could also be done by any high school student as a simple introduction to the physics of baseball. Mass has no effect on distance, but if you cant generate enough bat speed to overcome mass, you are doing yourself no favors and going backwards. /Height 99 /N 22 0 R A rough estimate would be that the ball rotates 1/4 revolution while it is in the pitchers hand, and while the hand moves forward say the last 0.2 m. If the hand moves forward at 10 m/s = 22.4 mph then it moves 0.2 m in 0.02 sec, so the spin rate would be 12.5 rev/s or 750 rpm. In Section 4, we present a dynamical model to modeling the sweet spot on a baseball bat. endobj The effect of the hands on the centre of percussion is described in American Journal of Physics, , 622-630 (2004). The fundamental mode of a wood bat has a node located typically about 17 cm from each end and a frequency typically of about 170 Hz. /V 9 0 R The shoulders reach maximum speed first, then the upper arms, then the forearm and finally the bat. throughout the paper. The science of magnetism, while not as well-known as the science of moving energy when a bat hits a ball, is still important in the game. /P 14 0 R By maintaining the same swing speed with a heavier bat, players can increase bat speed and distance in the same manner. 1) Hit with the label up Manufacturers always place the label on the face of the grain. /P 4 0 R If you hit the ball on the bats node, the vibrations from the impact will cancel out, and you wont feel any stinging or shaking in your hand. The sweet spot is typically located around the center of the bat, and its size varies depending on the type of bat being used. Joe Jackson, a shoeless man, would prefer a custom-built bat known as Black Betsy. A bat with an end loaded weight indicates that it weighs between 30 and 28 ounces. Ball Hysteresis.- 10. << /N 6 0 R If the ball didn't bounce at all then COR would be zero. A hollow aluminum bat sounds a lot different to a solid bat since the wall of a hollow bat can vibrate in and out like a drum. Subscribe to get special offers, free giveaways, and once-in-a-lifetime deals. << /R [52 73 308 791 ] Ball exit speed = (1 + q)V where V = bat speed at impact point just before the impact. Wind farms have different impacts on the environment compared to conventional power plants, but similar concerns exist over both the noise produced by the turbine blades and the . [/CalRGB /V 6 0 R /N 19 0 R Rather, the physics depends more on the ratio of the bat and ball speeds, regardless of whether the actual speeds are around 1 mph or 100 mph. Baseball players were known to carve or whisk their own bats from various hardwoods during the early days of amateur baseball. Sniper Skin carries a line of great bat grips which are easy to install and remove while virtually eliminating the sticky gunk left on your bat. According to Science Daily, human hands are sensitive to vibration frequencies between 200-700 hertz and we experience the most pain when those frequencies are between 600-700 hertz. >> Second, we give a simplified abstract form of bat which facilitates the description and modeling study. Only a small fraction of that huge force gets back to the handle to trouble the batter. /Matrix [0.4497 0.2446 0.02518 0.3163 0.672 0.1412 0.1845 0.08334 0.9227] The weight and construction of a bat also affects the bounce factor q, and it affects the time and position of the bat at which the swing speed is a maximum. Ball exit speed = q*vin where vin = incident ball speed. Baseball bats are an integral part of the game of baseball, and their physics is an important aspect of the sport. When Your Dream (Team/School/Job) Says "No". Sara Chodosh If you are 91 to 120 pounds, it is recommended that you use a 29-inch bat. >> If the ball is struck at the sweet spot of the bat, then . Strike at 12 cm Strike at 17 cm Strike at 24 cm Strike at 31 cm. A paper on this subject can be downloaded here. Why does hitting a baseball on the sweet spot of a bat result in a better hit than other parts of the bat? << But the bat vibrates strongly for impacts near the tip of the bat and near its center of mass. Analytical cookies are used to understand how visitors interact with the website. On average, players aged 15 to 17 hit 140 feet, while players aged 16 to 18 hit 150 feet, and players aged 18 to 19 hit 165 feet. Generally, heavier bats are used for power hitters, as they are able to generate more force when swinging. It is not easy to find information on the actual rate of spin of a softball in flight, but it is relatively easy to measure, at least at low ball speeds and low spin speeds. Whenever an object is struck, it vibrates in response. I simply wanted to know whether a hand launched ball spins at around 100 rpm or whether it could be as high as 1000 rpm. When one object collides with another, some of the energy from the impact goes into vibrational waves that travel through each object. So, after a rainy day game, ensure your bat is dry before you store it. q is also called the apparent coefficient of restitution or ACOR. It is critical not only for the sake of performance, but also for the sake of safety. This area is a product of physics, as the sweet spot is located at the center of percussion, which is the point on the bat that produces the least amount of vibration when hit. The ball rotated more than 1/4 but less than 1/2 of one revolution from one frame to the next, each frame being 0.04 sec apart. As such, aluminum baseball bats do not have a fixed point. So, well hit balls are struck at the sweet spot. It's where the wood grain is strongest. Maple bats are the most durable and have a larger sweet spot, making them ideal for power hitters. As a result, the bounce is relatively weak at the tip and near the center of mass. Uncovering The Mystery Behind The Golden Glove Award What It Takes To Receive This Prestigious Honor, How To Restring A Rawlings Baseball Glove Web: A Step-by-Step Guide, Exploring The Meaning Behind The Phrase Peanut Butter Jelly With A Baseball Bat. Where is the sweet spot on a bat? Upon impact with the ball, the rotation of the bat is reversed. Alan Nathan has the world's best Physics of Baseball site at, Another very interesting Physics of Baseball and Softball site is maintained by Dan Russell at, Lloyd Smith at Washington State University has an excellent site on the physics and engineering of softball, at. In principle you could also work out the acceleration due to gravity in Sydney, but not very accurately. That is, a large fraction of the stored elastic energy in the wall is retained as vibrational energy in the bat. /R [316 73 572 791 ] The hitch is, no one knows for sure how close the optimal spot for hitting is to the sweet spot that players know and love. A question that is equally interesting is how the swing speed of each body segment varies as the bat speed varies and as the bat swing weight varies. For small swings of a pendulum, the incoming and outgoing speed of the pendulum bob is proportional to its horizontal displacement, so the relevant ball speed ratios can be measured directly off the film with a ruler. From that you can work out the speed and spin of the ball before and after it bounces. /R [52 73 308 791 ] However, the COP shifts a long way toward the handle when a batter holds the handle, and plays only a minor role in the feel of the bat for an impact at the sweet spot. So, if you make sure the label is up, it means that you will be making contact with the edge of the grain which is the strongest part. Definition. /N 12 0 R Batters know from experience that there is a sweet spot on the bat, about 17 cm from the end of the barrel, where the shock of the impact, felt by the hands, is reduced to such an extent that the batter is almost unaware of the collision.
