You use a lever to lift a heavy tree branch. You apply a force of 30 N and the
lever lifts the branch with a force of 120 N What is the mechanical advantage
of the lever?

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.
