$5-5$ For a plate cam with translating offset roller follower shown in Fig. P$5-2,$ offset

$e=10mm,$ radius of the base circle $r_0=40mm,$ radius of roller $r_T=10mm,$ lift $h=20mm.$

The follower has the motion, a rise with cosine acceleration motion curve during $=150,$ s

$=30,$ a return with constant acceleration and deceleration motion curve during ${}^{\text{'}}=120,{}^{\text{'}}$

$=60.$ Draw the displacement diagram of the follower and the cam contour by graphical

method.
