Two 10-lb blocks A and B are connected by a slender rod of negligible weight. The coefficient of static friction is 0.30 between all surfaces of contact, and the rod forms an angle θ = 30° with the vertical, (a) Show that the system is in equilibrium when P = 0, (b) Determine the largest value of P for which equilibrium is maintained.
