Slider-crank mechanism: rotation into reciprocation
The rotating crank drives piston-like straight-line reciprocation. With the guide through the ground pivot, stroke is twice crank length a. Changing connecting-rod length b changes the positions and velocities between the endpoints.

What to watch in this mechanism
The rotating crank drives piston-like straight-line reciprocation. With the guide through the ground pivot, stroke is twice crank length a. Changing connecting-rod length b changes the positions and velocities between the endpoints.
Blue is the prescribed input, green is the connecting link and red is the output. Change the blue dimensions, then use the button to return to the drawing. This page calculates motion, not the required motor force or torque.
