3. A 200 lb man climbs up the ladder and stops at the position shown after sensing that the ladder is on the verge of slipping. Determine the inclination of the ladder if the coefficient of static friction between the friction pad A and the ground is u = 0.4. Assume that the coefficient of static friction at the wall is µ = 0. Assume the center of gravity of the man is at G. Neglect the weight of the ladder. -4 ft- G 12 ft A

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.
