The top box weighs 125 lbs. and the bottom box weighs 150 lbs. The coefficient of static friction between the boxes is? = 0.6. The coefficient of static friction between the bottom box and the floor is 0.35. What force, P will cause movement of one or more of the boxes? Does it tip or slip? (Hint: You must determine the minimum force to get the top box to slide;

Laws of Equilibrium

A body is said to be in equilibrium if the system of forces acting on the body tends to keep the body at rest, in other words, there is no translation motion or net torque on the body. Under such conditions, the equilibrium conditions are to be applied to analyze the condition. The branch of mechanics that deals with this condition is known as 'statics'. Under equilibrium, there are no net forces on the body.
