Question

Each of the two drums and connected hubs of 8-in. radius weighs 200 lb and has a radius of gyration about its center of 15 in. Calculate the angular acceleration of each drum. Friction in each bearing is negligible.

Answer 1

The angular acceleration of each drum is zero.

Step-by-step explanation:

To calculate the angular acceleration of each drum, we can use the formula:

angular acceleration = torque / moment of inertia

In this case, the torque is zero because the friction in each bearing is negligible. So the angular acceleration of each drum is zero.
