Each of the two drums and connected hubs of 8-in. radius weighs 225 lb and has a radius of gyration about its center of 23 in. Calculate the magnitude of the angular acceleration of each drum. Friction in each bearing is negligible.

The magnitude of the angular acceleration of each drum is .

Explanation:

We know that,

where,   r = hub radius,        M = mass of the drum,

             K = radius of gyration,     = angular gyration

                T = ........ (1)

Now,  

         23 lb - T = m()

                 23 =

Therefore, we can conclude that the magnitude of the angular acceleration of each drum is .

a electronegativity decreases beacuse the size of nucleus is bigger.
