Question: The tractor exerts a towing force T = 4 0 0 l b . It has a weight of 8 5 0 0 lb and

The tractor exerts a towing force T=400lb. It has a weight
of 8500 lb and a center of gravity located at GT. An
additinal weight of 600 lb is added to its front having a center
of gravity at GA. Take s=0.4. The front wheels are free to
roll.
a. Determine the normal reactions at each of the two front tires
b. Determine the normal reactions at each of the two rear tires
c. Determine the tractive frictional force F on each rear tire needed to pull the load forward at constant velocity
