Valve Cam Exercise Problem Statement Open Valve_Cam.sldasm The valve cam model pictured above includes a spring that will be added between the valve guide and the valve. The camshaft will be rotated at an angular velocity of 36,000 deg/s. Define Moving and Ground parts. Using curve/curve contact, create a spring with the correct stiffness and free length so that the camshaft and rocker are always in contact. We are going to plot the: Cam and Rocker contact force Valve and Rocker contact force Valve and cam contact force
