(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

W = 20 lb

k = 50 lb/ft

r = 4 in.

Initially displaced 0.5 in.

Determine the frequency and maximum velocity of the wheel (which rolls without slipping).

2. Relevant equations

(theta) double dot + (w^2)theta = 0

(x) double dot + (w^2) (x) = 0

t = 2*pi / w

3. The attempt at a solution

I wrote out the initial information. The amplitude is 0.5 in. I didn't know which equation to use (the one with theta or with x). But I used the one with x and wrote out the moment balance and force balance, only to find that I was off.

I thought to use the theta equation, but I cannot figure out where to go with it. I know alpha = theta double dot. x = r(theta), but I don't know where to go from that either.

Any help and direction would be awesome! I have 2 other problems, but just understanding this one might get me going on the others.
