1. A 165 lb man is climbing a 5.0 m-long uniform ladder weighing 25 lb, as shown below. The coefficient of static friction between the wall and the ladder is 0.20 and the coefficient of static friction between the ladder and the ground is 0.25. Using USCS units, determine; a) how far up the ladder the man can climb before the ladder starts to slip, and FIGURE CREDIT: Statics and Mechanics of Materials, Riley, Sturges and Morris, 2nd ed. b) what additional minimum weight applied directly at the base of the ladder would enable the man to reach the top of the ladder without slippage.
