Problem 2
The curved, slender bar OC rotates about point O. At the instant shown, the angular velocity of OC has a
constant value of 2 rad/s in the direction shown. Use a rotating axes analysis to find the angular velocity
of bar AB, the velocity of B with respect to the bar OC, and the angular acceleration of bar AB. Clearly
show the location and direction of your axes, as well as your choice of ?. (Hint: ? should be the angular
velocity of bar OC, and the axes should be at point O.) (Answer: $\omega_{AB}$=0 rad/s, $\vec{v}_{xy}$ = 32 î in/s, $\alpha_{AB}$=7.4
rad/s² CCW)
