# Period of Precession [closed]

I'm trying to find the period of precession for a gyroscope. Now I was able to find the angular precession rate, which was 1.132 rad/s, but I have no idea how to convert this to a 'period', and google didnt find me anything useful. How do I do this?

Quick advice: add units when you write numbers ! – Cedric H. Nov 7 '10 at 22:43

If your rate is $\omega_p$ given in rad/s then the period is $\frac{2 \pi}{\omega_p}$ with units of seconds.

Ya I was able to get the same thing from wolfram wolframalpha.com/input/?i=1.132+radians/second thanks though! – maq Nov 7 '10 at 22:47
@Cedric: This is of course correct, but we do not recommend here that direct answers be given to homework questions. Hints (to some level) are always preferred. – Noldorin Nov 7 '10 at 22:47
You're right, sorry. I first tried to answer explaining frequency, period and angular frequency, but my explanation was not clear at all. – Cedric H. Nov 7 '10 at 22:50
@frime: Well in any case, I think you would have gotten the answer from either mine or Cedric's responses. ;) – Noldorin Nov 7 '10 at 22:59
@fprime: I was referring to people in general. I suggest you start showing a bit of respect here, especially to those answering your questions, or you won't do very well. It's a community, remember. – Noldorin Nov 7 '10 at 23:37

Hint:

Angular velocity is related to angular frequency by a constant factor. Period and frequency also have a simple (inverse) relation. Combine the two.

We both got a +1 and a -1, I can understand mine, but why -1 here ? – Cedric H. Nov 7 '10 at 22:53
Why the down-vote? – Noldorin Nov 7 '10 at 22:53
@Cedric: I initially down-voted yours, but now I realise it was an innocent action, I tried to undo it... Unfortunately, silly StackExchange won't let me. – Noldorin Nov 7 '10 at 22:54
No worries. – Cedric H. Nov 7 '10 at 22:56
