A good workout would burn about 100,000 joules of chemical energy. Suppose you wanted to push a sofa with a force of 1600 Newtons as exercise. How far would you need to push the sofa for you to get a good workout?

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.
