The physics of baseball Baseball players know from experience that there is a ``sweet spot'' on a baseball bat, about 17cm from the end of the barrel, where the shock of impact with the ball, as felt by the hands, is minimized. In fact, if the ball strikes the bat exactly on the ``sweet spot'' then the hitter is almost unaware of the collision.

The distance is the moment arm, often denoted by r. It is a vector pointing from the axis of rotation to where the force acts. In order to produce more torque, you need to apply force further from the pivot point or apply more force. As Archimedes said, given a place to stand with a long enough lever…

Lever The lever arm consists of a lever (rigid rod) and a fulcrum (where the center of rotation occurs). The torque is the same at all positions of the lever arm (both on the same side and on the other side of the fulcrum). If you apply a force at a long distance from the fulcrum, you exert a greater force on a position closer to the fulcrum.

Angular momentum is a vector. For a single particle its direction is the direction of the angular velocity (given by the right hand rule). The angular momentum of an object is changed by giving it an angular impulse.An angular impulse ΔL is a change in angular momentum. You give an object an angular impulse by letting a torque act on it for a time interval Δt.

A force applied perpendicularly to a lever multiplied by its distance from the lever's fulcrum (the length of the lever arm) is its torque.A force of three newtons applied two metres from the fulcrum, for example, exerts the same torque as a force of one newton applied six metres from the fulcrum. The direction of the torque can be determined by using the right hand grip rule: if the fingers ...

May 12, 2013· The general idea of a lever arm is to maximise the ratio of input force to output force. If a force is acted on the beam further from the pivot point it will cause more motion than if it was closer because the linear velocity of an object is larger the greater the radius of ration is.

Jan 06, 2020· Thus, larger hip adduction would increase the HAM impulse by increasing the lever arm between the hip joint center and GRF vector. In muscle-driven gait simulations, an increase in hip adduction was shown to be the most influential kinematic affecting the increase in peak HAM and the hip contact force [ 18 ].

An escapement is a mechanical linkage in mechanical watches and clocks that gives impulses to the timekeeping element and periodically releases the gear train to move forward, advancing the clock's hands. The impulse action transfers energy to the clock's timekeeping element (usually a pendulum or balance wheel) to replace the energy lost to friction during its cycle and keep the timekeeper ...
