Angular Speed of Ceiling Fan, w = 3.56 rad/s
Fictional Torque when turned off, T = 0.105 N.m
The Time elapsed i.e., total time of fan rotating, t = 31.3 s
We have an equation for the Moment of inertia i.e., J = (T x t) / w
J = (0.105 x 31.3) / 3.56 => J = 3.286 / 3.56 = 0.92
So Moment of inertia J = 0.923
