The sports car has a mass of 1.5 Mg and mass center at G. If the front two springs each have a stiffness of kA=58 kN/m and the rear two springs each have a stiffness of kB = 65 kN/m, determine their compression when the car is parked on the 30° incline. Also, what frictional force FB must be applied to each of the rear wheels to hold the car in equilibrium?
[A]. xA = 16.1 mm, xB = 42.2 mm, FB = 6.37 kN
[B]. xA = 65.9 mm, xB = 39.2 mm, FB = 6.37 kN
[C]. xA = 53.2 mm, xB = 50.5 mm, FB = 3.68 kN
[D]. xA = 76.1 mm, xB = 45.3 mm, FB = 3.68 kN
