A large grinding wheel in the shape of a solid cylinder of radius 0.330 m is free to rotate on a frictionless, vertical axle. a
constant tangential force of 260 n applied to its edge causes the wheel to have an angular acceleration of 0.810 rad/s2. (a) what is the moment of inertia of the wheel?
Let I = the moment of inertia of the wheel. α = 0.81 rad/s², the angular acceleration r = 0.33 m, the radius of the weel F = 260 N, the applied tangential force
The applied torque is T = F*r = (260 N)*(0.33 m) = 85.8 N-m
