Two small rings O and O’ are put on two vertical stationary rods AB and A’B’, respectively. One end of an inextensible thread is tied at point A’. The thread passes through ring O’ and its other end is tied to ring O. Assuming that ring O’ moves downwards at a constant velocity v1, then velocity v2 of the ring O, when ∠AOO’=α

A U-shaped smooth wire has a semi-circular bending between A and B as shown in fig. A bead of mass m moving with uniform speed v through the wire enters the semiculcular bent at A and leaves at B. Find the average force exerted by the bead on the part AB of the wire.
