Subject: YP Slider Crank 1.1
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.
