Activity 1. A 25-kg ladder, 4 m long, rests on a rough floor and against a vertical wall. The ladder makes an angle of 35° with the horizontal as shown. It starts to slip when a man weighing 75 kg has climbed halfway up. If f = 0.20 at the wall, find the coefficient of friction (u) at the floor. 75 Kg 2m 2m 7w=25Kg 35° right? The coefficient of friction is 0.10 and the pulleys are assumed to be frictionless. (b) (a) 400# 600# 30°

You need to move a cubic crate across a rough floor. You pull the crate horizontally using a rope with force F, as shown in Figure 1. The weight of the crate is 700 lb:, its density is 180 lbm/fts, and the coefficient of static friction between the crate and the floor is 0.57. Write an expression for the maximum static friction force fmax (in lb:) as a function of the mass m of the crate. Use Excel to plot fmax(m). Calculate the average pressure of the crate on the floor, in psi. Calculate the minimum force F necessary for the crate to start moving, in lb;. F Figure 1. Moving a crate on a slope.
