The winch cable on a tow truck is subjected to a force of T = 6 kN when the cable is directed at θ = 60°. Determine the magnitudes of the total brake frictional force F for the rear set of wheels B and the total normal forces at both front wheels A and both rear wheels B for equilibrium. The truck has a total mass of 4 Mg and mass center at G.
