The tractor has a weight of 8000 lb with center of gravity at G. Determine if it can push the 550-lb log up the incline.The coefficient of static friction between the log and the ground is µs = 0.5 , and between the rear wheels of the tractor and the ground µœ s = 0.8 . The front wheels are free to roll. Assume the engine can develop enough torque to cause the rear wheels to slip.
