Question

A wheel rotates without friction about a stationary horizontal axis at the center of the wheel. A constant tangential force equal to 83.0 is applied to the rim of the wheel. The wheel has radius 0.110 . Starting from rest, the wheel has an angular speed of 14.6 after 3.26. What is the moment of inertia of the wheel?

Answer 1

Strategy:
1) From known angular speed and time, find angular acceleration:\[\omega=\alpha t\] 2) From known torque and angular acceleration found in (1), find I \[\tau=I\alpha\] where \[\tau=Fr\]

Answer 2

Is the answer 2.04kg*m^2

Answer 3

\[I=\frac{ Frt }{\omega}\] right?

Answer 4

Correct!
