Figure 10.88 shows an eccentric cam mated with a flat-faced follower of mass m_f. Conduct a force analysis on this system and find an expression for the contact force between cam and follower as a function of cam angle θ. The spring has stiffness k, and is in its neutral position when θ = 180°; that is, when the follower displacement is at a minimum. Assume that there is no friction between cam and follower, or between the follower and its guide bushing. The cam rotates at a constant angular velocity, ω. At which angular velocity will the contact force between cam and follower vanish if the cam is at θ = 0°?
