A compact disc rotates from rest up to an angular speed of 34.3 rad/s in a time of 0.867 s.
(a) What is the angular acceleration of the
disc, assuming the angular acceleration is uniform?
rad/s2
(b) Through what angle does the disc turn while
coming up to speed?
rad

Rod OA rotates counterclockwise with a constant angular velocity
of = 5 rad/s. The double collar B is pin connected together such
that one collar slides over the rotating rod and the other slides
over the horizontal curved rod, of which the shape is described by
the equation r = 1.5(2 - cos θ) ft. If both collars weigh 0.75 lb,
determine the normal force which the curved rod exerts on one
collar at the instant θ = 120o. Neglect...
