The crane truck has a weight of 14250 lb and a center of gravity at point CG. The parking brake only locks the rear wheels of the truck, so the front wheels are free to rotate. Determine the maximum force F applied at the angle = 39° that can be exerted on the crane without it slipping or tipping for each of the following cases: Case 1: The static friction coefficient between the rear tires and the ground is μ = 0.080. Case 2: The static friction coefficient between the rear tires and the ground is μ = 0.41. d CGP a b a*
