Some external energy is added in the experiment by the bungee or weight pulling the pendulum stick through the impact. The player pushes down and forward, increasing and maintaining the bend until puck contact, which bends the stick further. Lidstrom was another who used a longer stick.So it really just depends. And, ironically, some players react to a stiffer stick by putting more force into bending it, so they get just as much or more velocity than they do with a softer stick.

These factors tend to be difficult to dissect and separate, given that they all interact so quickly. “It’s pretty awesome actually. The stiffness of graphite composite hockey sticks can be varied by altering the material and direction of fiber as well as altering the shape and thickness of the shaft. The stick then begins to snap back, transferring the stored elastic energy to the puck. Until scientific research has been conducted, these observations and beliefs may only be supported by perceptions and myths carried along by the sport for years. All the variables in the calculations are known except the one variable of interest in each equation — So the tangential, linear velocity of the tip before impact, This changes everything, tempting many observers to describe the interaction as more like a catch and a throw or a long push than like a collision. But usually we want them to be predictive. Thursday, August 13, 2020 The more stick flex, measured by flex time and flex angle, the faster the shot. During my time as Masters champion Mike Weir's swing coach, we would reference a slapshot motion in order to work on covering the ball better in the downswing. However, during puck contact, the snap-back tip velocity more than makes up for the lower contact velocity and the net tip and puck speed is greater at separation than in Figure 4. 27.07.2020 - Erkunde Paul-Phillips Pinnwand „Inline Hockey“ auf Pinterest. How to master the snapshot. Mass. In this case the real test would be if multiple sticks show the same flex (regardless of the number printed on the stick).I'm an engineer, albeit not a mechanical one. However, there is no unanimous agreement as to what flex profiles maximize puck speed. We can keep all input variables constant except one, and then see how that variable affects puck velocity. As the tip rotates and snaps forward, it strikes the puck, but at a significantly slower speed than in Figure 4. And what caused it — stick flex, weight, balance, curve, length, inertia or player technique? I think what's going on here is that they're using a very general beam deformation equation. Table 2 shows the stiffness and puck speeds resulting from these stiffness alterations. ... and a bit high than with the slapshot; I usually put my bottom hand close to the middle of the shaft. He uses a stick that's near his nose Datsyuks stick length is more typical of defensemen. 180lb = 90 flex etc. The stiffness of the stick was altered by attaching a second beam to the first with double sided tape or a bolt. HOLT: In slow motion, slap shot physics is revealed. In that sense the equations are descriptive and analytic. Another way to look at it is set-up/playmakers use stiff sticks, while scorers/shooters use sticks with more flex.Crosby uses a stiffer stick.

Hand position affects the stiffness because it determines the length of the bending arm between the ice and the hand. In one variation, a bungee cord pulled the pendulum arm through contact with the puck (100 g brass weight), regulating a constant speed and force of contact. The stiffness may be uniform throughout, or it can be varied at any location along the stick's length. He says that the flex number was very different to manufacturer markings because of wear, but I wonder if they aren't just sloppy. The 66% length beam was also less stiff, being only 2 mm thick instead of 3mm — The hand position was adjusted by sliding and tightening the angle brace labeled "lower hand" in Figure 1. That’s probably how I got here.” It is important to be clear about the definition of COR and of the variables in Equation 2.
