Calculate the torque required to bring to rest a rotating rod plus attached masses.

A uniform rod, length L= 1.50 m, mass M= 6.60 kg, has attached to each end a small mass m= 1.06 kg. Initially rotating about its c.m. axis at 48 rev/sec, is brought to rest in 15 seconds.
Find the net torque, T, which is required.

Note: The equation which relates torque T to angular acceleration A is:
(1) T = I A in which I is the moment of inertia of the accelerating object. Both the torque and the moment of inertia must be relative to the ...
