Blocks A and B are connected by a cable that passes over support

Blocks A and B are connected by a cable that passes over support C. Friction between the blocks and the inclined surfaces may be neglected. Knowing that motion of block B up the incline is impending when 8 kg, mB = determine

(a) The coefficient of static friction between the rope and the support,

(b) The largest value of B m for which equilibrium is maintained.
