Derive the governing equation of motion for the rocker-arm valve assembly shown below. Assume "small" motions. The quantity Jo is the mass moment of inertia about point O of the rocker arm of length (a + b), k is the stiffness of the linear spring that is fixed at one end, c is the damping coefficient of the linear damper, and M is the external moment imposed by the cam on the system. This moment is produced by the contact force generated by the cam at the end of the rocker arm.

The quarter-car model of a vehicle suspension and its free body diagram are shown in Figure 1. In this simpliﬁed model, the masses of the wheel, tire, and axle are neglected, and the mass m represents one-fourth of the vehicle mass. The spring constant k models the elasticity of both the tire and the suspension spring. The damping constant c models the shock absorber. The equilibrium position of m when y=0 is x=0. The road surface displacement y(t) can be derived from the road surface profile and the car’s speed. Draw free body diagram (FBD) and derive the equation of motion of m with y(t) as the input, and obtain the transfer function.
