Question 14 5 pts If each box weighs 120 lb, determine the horizontal force P (in units of lb) necessary to cause both boxes to tip as a single unit. The coefficient of static friction between the boxes is . -0.62, and the coefficient of static friction between the bottom box and the floor is H. -0.27. 4.5 ft 5 ft 4.5 ft
If each box weighs 160 lb , determine the least horizontal force P that the man must exert on the top box in order to cause motion. The coefficient of static friction between the boxes is μs = 0.80, and the coefficient of static friction between the box and the floor is μ′s = 0.25. (Figure 1) -3 ft 4.5 ft 5 ft 4.5 ft А B
