Solve for ONE turn around the tree.
8-85. A 180-lb farmer tries to restrain the cow from escaping by wrapping the rope two turns around the tree trunk. If the cow exerts a force of 250 lb on the rope, determine if the farmer can successfully restrain the cow. The coefficient of static friction between the rope and the tree trunk is s=0.15, and between the farmer's shoes and the ground s'=0.3.
