18. Problem 11.45E (HRW) Calculate the rotational inertia of a wheel that has a kinetic energy of 24,400 J when rotating at 602 rev/min. |
|
Solution: Click For PDF Version The angular speed of the wheel in rad/s will be
The rotational kinetic energy is
|
.
, where
I is the rotational inertia. As the kinetic energy of the wheel is 24,400 J,
its rotational inertia will be
.
