Question
Q.4: Determine the pitch (angular motion) and bounce (up-and-
down linear motion) frequencies and the location of oscillation
centers (nodes) of an automobile in fig.(4) with (J=mr). (note
that to neglect the effects of dampers)
Mass (m) = 1000 kg
Radius of gyration (r) 0.9 m
Distance between front axle and C.G. (L) 1.0 m
Distance between rear axle and C.G. (L2) = 1.5 m
Front spring stiffness (kr) = 18 kN/m
Rear spring stiffness (k;) = 22 kN/m
