Repeat Problem 15-12 using a cam with a 20-mm symmetric double harmonic rise and fall (180° rise -180° fall). See Chapter 8 for cam formulas.
Problem 15-12
The cam in Figure P15-2 is a pure eccentric with eccentricity= 20 mm and turns at 200 rpm. The mass of the follower is 1 kg. The spring has a rate of 10 Nlm and a preload of 0.2 N. Find the follower force over one revolution. Assume a damping a ratio of 0.1 0. If there is follower jump, respecify the spring rate and preload to eliminate it.
