Answer to Question #345817 in Mechanical Engineering for beab

Question

One of the wheels and leaf springs of an automobile, traveling over a rough road, is

shown in Figure 1 below. For simplicity, all the wheels can be assumed to be

identical and the system can be idealized as shown in Figure 2 below. The

automobile has a mass of m1 = 1000 kg and the leaf springs have a total stiffness of

k1 = 400kN/m. The wheels and axles have a mass of m2 =300kg and the tires have

a stiffness of k2= 500kN/m. If the road surface varies sinusoid ally with an

amplitude of Y = 0.1 and a period of l = 6m find the critical velocities of the �
