Question

If DC has the constant angular speed shown, determine the angular acceleration of AB and BC at the instant shown. CD is vertical and BC is horizontal.

Answer 1

The angular acceleration of AB and BC at the instant shown is zero.

Step-by-step explanation:

For the given problem, we need to determine the angular acceleration of AB and BC at the instant shown when DC has a constant angular speed. Since the angular speed of DC is constant, it means its angular acceleration is zero. Therefore, the angular acceleration of AB and BC at the instant shown is also zero. This is because there is no change in the angular speed over time, indicating no angular acceleration.
