Solved: The tractor exerts a towing force T = 400 lb.
Chapter 8, Problem 8-2(choose chapter or problem)
The tractor exerts a towing force T = 400 lb. Determine the normal reactions at each of the two front and two rear tires and the tractive frictional force F on each rear tire needed to pull the load forward at constant velocity. The tractor has a weight of 7500 lb and a center of gravity located at \(G_{T}\). An additinal weight of 600 lb is added to its front having a center of gravity at \(G_{A}\). Take \(\mu_{\mathrm{s}}=0.4\). The front wheels are free to roll.
