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 ?_s = 0.5, and between the rear wheels of the tractor and the ground ?_s? = 0.8. The front wheels are free to roll. Assume the engine can develop enough torque to cause the rear wheels to slip.
