The frame of mass m is welded together from uniform slender rods. The frame is released from rest in the upper position shown and constrained to fall vertically by two light rollers which travel along the smooth slots. The roller at A catches in the support at O without rebounding and serves as a hinge for the frame as it rotates thereafter. Determine the angular velocity of the frame an instant after the roller at A engages the support at O.
