Question:
The 5-in.-radius cam shown is used to control the motion of the plate CD. Knowing that the coefficient of static friction between the cam and the plate is 0.45 and neglecting friction at the roller supports, determine
(a) The force P for which motion of the plate is impending knowing that the plate is 1 in. thick,
(b) The largest thickness of the plate for which the mechanism is self-locking, (that is, for which the plate cannot be moved however large the force P may be).
