Two boys have a tug-of-war using a rope. In the process the rope rubs against a post such that it is deflected 3° on each side of the post. If boy A weighs 60 lb and boy B weighs 50 lb, determine if it 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 boys’ shoes and the ground is μ_p = 0.4.
