The uniform thin pole has a weight of 30 lb and a length of 26 ft. the coefficient of static friction is μs = 0.3. if it is placed against the smooth wall and on the rough floor in the position d = 10 ft, will it remain in this position when it is released? (f

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.
