soppose a force of 100n is applied to a piston with a cross section area of .0005 m2. what will be the force out if the size of the piston was .01 m2

The 20@kg wheel has a radius of gyration about its center g of kg = 300 mm. when it is subjected to a couple moment of m = 50 n # m, it rolls without slipping. determine the angular velocity of the wheel after its mass center g has traveled through a distance of sg = 20 m, starting from rest.
