In the figure below, two blocks are connected to each other by a massless string over a frictionless pulley. The mass of the block on the left incline is 6.00 kg. Assuming the coefficient of static frictions equals 0.542 for all surfaces, find the range of values of the mass of the block on the right incline so that the system is in equilibrium.
minimum mass for equilibrium     kgmaximum mass for equilibrium     kg

Solution

Apply the equilibrium equation to block M
