Question 2 (CLO 1, PLO 2, C3) A rough sketch of a valve-and-rocker arm system for an internal combustion engine is given in Figure OHT 1-1. Model the system as a pendulum attached to a spring and a mass and assume the oil provides viscous damping in the rage of 0.01. Determine the equations of motion and calculate an expression for the natural frequency and the damped natural frequency. Here J is the rotational inertia of the rocker arm about its pivot point, k is the stiffness of the valve spring, and m is the mass of the valve and stem. Ignore the mass of the spring.
