Ablock of a certain material begins to slide on an inclined plane when the plane is inclined to an angle of 18.26°.
if a solid cylinder is fashioned from the same material, what will be the maximum angle at which it will roll without slipping on the plane?

Two steel balls, each of mass m, are welded to a light rod of length l and negligible mass and are initially at rest on a smooth horizontal surface. a horizontal force of magnitude f is suddenly applied to the rod as shown. determine (a) the instantaneous acceleration a of the mass center g and (b) the corresponding rate at which the angular velocity of the assembly about g is changing with time.
