1.Where does the potential energy in the lever arm come from?

2.Where is there POTENTIAL ENERGY throughout the loading, cocking, and releasing of the trebuchet?

3.Where is there KINETIC ENERGY throughout the loading, cocking, and releasing of the trebuchet?

A200-n force is applied to the foot-operated air pump. the return spring s exerts a 2.6-n·m moment on member oba for this position. determine the corresponding compression force c in the cylinder bd. if the diameter of the piston in the cylinder is 40 mm, estimate the air pressure generated for these conditions. state any assumptions. enter a positive number for the compression force c.
