Three masses M_(1), M_(2) and M_(3) are lying on a frictionless table. The masses are connected by massless threads as shown. The mass M_(3) is pulled by a constant force F as shown. The tension in the thread between masses M_(2) and M_(3) is

The intial configuration of the system is as shown in the figure. The string and the pulley are light. The bob is released and the string starts wrapping around the pulley. (The pulley is held in place by a force applied at the centre) Find the rate r at which the length of the string warpped around the pulley increaes (as a function of theta ).

A uniform solid cylinder of mass m rests on two horizontal planks. A thread is wound on the cylinder. The hanging end of the thread is pulled vertically down with a constant force F . Find the maximum magnitude of the force F which may be applied without bringing about any sliding of the cylinder, if the coefficient of friction between the plank and the cylinder is equal to mu . What is the maximum acceleration of the centre of mass over the planks?

A block of mass m is connect to another block of mass M by a massless spring of spring constant k. The blocks are kept on a smooth horizontal plane. Initially the blocks are at rest and the spring is upstretched when a constant force F starts acting on the block of mass M to pull it. Find the maximum extension of the spring.
