Yes, good.The moment arm gets longer for b*sinφ, ok?
Yes.On the other side it gets shorter for b*sinφ
Why is that?But when talking about small φ that has no sense
That's going too far in the approximation.sin φ ≈ 0 for small φ
So, to first order in φ?sinφ=φ-(φ^3)/6
That's right.oh it is φ
Yes, there is no oscillation. Looking back at your post#43, I think you need to add an overall negative sign to the first equation so that it'sω^{2} is then negative, so there is no oscillation in real?
