The reciprocating radial roller follower of a plate cam profile with 0.7 in offset is to rise 2 in with simple harmonic motion in 180 degrees of cam rotation and return with simple harmonic motion in the remaining 180 degrees. If the roller radius is 0.375 in and the prime-circle radius is 2 in, construct the displacement diagram, the pitch curve, and the cam profile for clockwise cam rotation.
