Ex.5-1 A plate cam with positive-offset translating roller follower is to have the following motion: a rise through lift h=40mm with a sine acceleration motion curve during 0=150 , S=30 , a return with a 3-4-5 polynomial motion curve during 0=120 , and S=60 . The cam rotates clockwise. The given dimensions are: rP=40mm. rR=12mm, e=12mm and rC=25mm. Construct the pitch curve and the cam contour graphically with a scale of 1:1. Label in red ink the centreline of the follower, S, the roller and the
