Two blocks, A of mass m and B of mass M, m < M, sit on a rotating turntable, as shown in the diagram below. The blocks are connected by a light string over a frictionless pulley. Block A has mass m and block B has mass M, where m < M. The blocks are a distance R from the axis of rotation on a turntable. The coefficient of static friction between the blocks and between the blocks and the turntable is µ. The angular velocity w of the turntable is slowly increased until it reaches a critical value w. when the heavier block B slips outwards.
