Two boys have a tug-of-war using a rope. In the process the rope rubs against a post such that it is deflected 3º on each side of the post. If boy A weighs 60 lb and boy B weighs 50 lb, determine if it is possible for one of them to pull the rope toward him. The coefficient of static friction between the rope and the post is μ_P = 0.3, and the coefficient of static friction between the shoes of the boy at A and the ground is μ_A = 0.4, whereas for boy B it is μ_B = 0.5.
