Transcribed Image Text: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
0 = 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
