A 2.0-m-high box with a 1.0-m-square base is moved across a rough floor as in Fig. 9–89. The uniform box weighs 250N and has a coefficient of static friction with the floor of 0.60. What minimum force must be 1.0 m exerted on the box to make it slide? What is the maximum height h above the floor that this force can be applied without tip- ping the box over? Note that as the box tips, the normal force CG 2.0 m FN and the friction force will act at the lowest corner. Fir FIGURE 9-89 Problem 74.
