Unformatted text preview: A 120-lb cabinet is mounted on casters that can be locked to prevent their rotation. The coefficient of static friction between the floor and each caster is 0.30. If 32 in., h determine the magnitude of the force P required to move the cabinet to the right ( a ) if all casters are locked, ( b ) if the casters at B are locked and the casters at A are free to rotate, ( c ) if the casters at A are locked and the casters at B are free to rotate....
