Dear friends,(adsbygoogle = window.adsbygoogle || []).push({});

I'm having trouble with this problem, I don't know if I'm doing it right, I'd be grateful if you could advice me.

Two discs, each of mass M and radius R, are supported with equal

separation along a slender rod to which they are rigidly fastened at

their centers as shown in the picture I attached below.

I need to calculate the normal frequencies and normal modes.

This is what I've done:

T(kinetic energy)=1/2*1/2MR^2(theta1^2+theta2^2)

V(potential)=1/2*k(theta1^2+theta2^2+(theta1-theta2)^2

Where theta is the angle the disc turns. Does this make sense?

THanks!
