2. The vehicle in Fig, 2 has a m nass of 1.5 Mig and mass center at G. If the front two springs each have a stiffness of k_A = 58 kN/m and the rear tw wo springs each have a stiffness of k_B = 65 kN/m. Determine their compression when the car is parked on a 30°incline. Additionally, what friction force F_B must be applied to each rear wheel to hold the vehicle in equilibrium? (35%)
