Problem 5 friction , two blocks connected with horizontal rigid bar, Engineering mechanics

Описание: Two blocks connected by horizontal rigid bar AB are supported on two rough planes . The coefficient of friction between black A and horizontal surface is 0.39. The limiting angle of friction between block B and inclined plane is 20°. The weight of Block B is 5 N. Find the smallest weight W of the block A for which equilibrium of system exists?
