Two 2.6-1b collars A and B can slide without friction on a frame, con- sisting of the horizontal rod OE and the vertical rod CD, which is free to rotate about CD. The two collars are connected by a cord running over a pulley that is attached to the frame at O, and a stop prevents collar B from moving. The frame is rotating at the rate 0 = 12 rad/s and r = 0.6 ft when the stop is removed, allowing collar A to move out along rod OE.

![12.92 Two 2.6-lb collars A and B can slide without friction on a frame, con-
sisting of the horizontal rod OE and the vertical rod CD, which is free
to rotate about CD. The two collars are connected by a cord running
over a pulley that is attached to the frame at O, and a stop prevents
collar B from moving. The frame is rotating at the rate 0 = 12 rad/s
and r = 0.6 ft when the stop is removed, allowing collar A to move out
along rod OE. Neglecting friction and the mass of the frame, deter-
mine, for the position r = 1.2 ft, (a) the transverse component of the
velocity of collar A, (b) the tension in the cord and the acceleration of
collar A relative to the rod OE.
