Problem
Answer published by the source. Consult the official source to check your work against its answer.
question
A plate cam causes a reciprocating roller follower to execute asimple harmonic motion with a maximum displacement of 2 in.The motion comprises of a rise for 140° and a fall for 160° of the cam rotation.The follower's roller is 1 in. in radiusand the pressure angle should not exceed 35°. Evaluate: (1)theperpendicular distance between the follower axis and thecamshaft axis. (2)thesmallest possible size of the cam for noiseless and efficientfunctioning of the cam.
