In the following model, drag Point E along the circle to simulate the pump jack. Don't forget to PLAY with the four parameters and the position of Point D and Point A.
In this we take the Crank value as 1.5 and now we can move Point E.
In this we take the leftBeam as 4.9 and now we can move Point E.
In this we take the pitman value as 2.9 and now we can move Point E.
In this we take the rightBeam as 2.5 and now we can move Point E.
