Find the mass m in the figure for the system to be at rest

In arrangement shown below, the thread pulley and spring are all massless and there is no friction anywhere. The system is in equilibrium. If thread connecting m_(4) is cut then just after thread is cut :

A smooth block of mass m is held stationary on a smooth wedge of mass M and inclination theta as shown in figure .If the system is released from rest , then the normal reaction between the block and the wedge is

A smooth rod is fixed at an angle alpha to the horizontal. A small ring of mass m can slide along the rod. A thread carrying a small sphere of mass M is attached to the ring. To keep the system in equilibrium, another thread is attached to the ring which carries a load of mass m_(0) at its end (see figure). The thread runs parallel to the rod between the ring and the pulley. All threads and pulley are massless. (a) Find m_(0) so that system is in equilibrium. (b) Find acceleration of the sphere M immediately after the thread supporting m_(0) is cut.
