Yp Slider Crank

YP Slider Crank simulates the motion of a piston activated by a slider crank mechanism. The crank is in uniform rotational motion (constant angular velocity), causing the piston to move with a variable acceleration. Relative lengths of the crank arm and the connecting rod may be changed easily. During the simulation, it is possible to display the following vectors: acceleration, velocity and position, and the following graphs: acceleration, velocity and position versus time. New in this version: To help understanding relative velocity, the animation can be viewed in 3 different reference frames. During the animation, the user can display a vector diagram showing how the velocity of the crank and the velocity of the connecting rod are combined together to give the velocity of the piston. A new "theory" window explains how to find the velocity of the piston.
