In the arrangement shown in figure the cylinder of mass M is at rest on an incline. The string between the cylinder and the pulley (P) is horizontal. Find the minimum coefficient of friction between the incline and the cylinder which can keep the system in equilibrium. Also find the mass of the block. Assume no friction between the pulley (P) and the string.

In the arrangement shown in figure, pulley and string are light. Friction coefficient between the two blocks is mu whereas the incline is smooth. Block A has mass m and difference in mass of the two blocks is deltam . Find minimum value of m for which the system will not accelerate when released from rest.

In the arrangement shown in the figure if the blocks of masses m and 2m are released from the state of rest tension in the string is ( mu = coefficient of friction string is massless and inextensible pulley is frictionless )

In the arrangement shown in the figure, the blocks have masses 3m,m and 2m , the friction is absent, the masses of the pulleys and the threads are negligible. Find the acceleration of mass 3m .
