Question
The assembly consisting of a uniform slender bar (mass = 1.5 kg and L = 0.49 m) and a rigidly attached uniform disk (mass = 6.8 kg) is
freely pinned to point O on the collar that in turn slides on the fixed horizontal guide. The assembly is at rest when the collar is given a
sudden acceleration a = 3.4 m/s² to the left as shown. Determine the initial angular acceleration a of the assembly. The angular
acceleration is positive if counterclockwise, negative if clockwise.
6.8 kg
Answer: a = i
1.5 kg
LA
