- Homework Statement
- The precession rate is given as ##Ω = \frac{Mgr}{Iω}##.

- Relevant Equations
- What are the units here?: I'm calculating it as ##\frac{1}{rad . s}##.

The precession rate is given as ##Ω = \frac{Mgr}{Iω}##.

What are the units here?: I'm calculating it as ##\frac{1}{rad . s}##.

Am I supposed to interpret this as revolutions per second, sort of like frequency, and ignore the ##rad##?

Also, period is calculated as: ##T = \frac{2π}{Ω}##. So, ##T##'s units are ##\frac{s}{rev}##?

I'm guessing that I don't quite understand yet how ##rads## are ignored in the calculations.

Edit: This refers to gyroscopic precession wherein gravity is the only force causing a torque.
