The  follower is attached to the end of a light telescopic rod that is pivoted at O. The follower is pressed  against a frictionless spiral surface by a spring of stiffness   and the free length  . The equation of spiral, which lies in the horizontal plane, is   , where         and   in radians. Immediately after the rod is released from rest in position OA, determine  (a) the angular acceleration  of the rod; and  (b) the contact force between the follower  and the spiral surface.

The 2.4 lbfollower is attached to the end of a light telescopic rod that is pivoted at 0. The follower is
pressed against a frictionless spiral surface by a spring of stiffness k = 8 lb/ft and the free length
Lo = 3 ft. The equation of spiral, which lies in the horizontal plane, is R = 22, where
1.2 ft and e in radians. Immediately after the rod is released from rest in position OA, determine
(a) the angular acceleration ö of the rod; and (b) the contact fore between the follower and the
spiral surface.
