Consider the tractor shown in (Figure 1). The front wheels are free to roll. The tractor weighs 5200 lb and has a center of gravity at G. Part A If the coefficient of static friction between the rear wheels of the tractor and the ground is μ =0.6, determine if the rear wheels slip or the front wheels lift off the ground as the engine provides torque M to the rear wheels. O the front wheels lift off the ground O the rear wheels slip Submit Part B Request Answer What is the torque needed to cause the motion? Express your answer in kilopound-feet to three significant figures. Enter positive value if the moment is counterclockwise and negative value if the moment s clockwise.
