How do i find the period of small oscillations and length of the equivalent simple pendulum, for a rectangular plate (edges a and b) suspended at its corner and oscillating in vertical plane?(adsbygoogle = window.adsbygoogle || []).push({});

T = 2pi (I/mgl)^1/2

i calculated l (length) to be (a^2 + b^2 )^1/2 ---(the diagonal) is this right?

I = m/3 (a^2 + b^2)

when i try to plug this into T though, it gets nasty and i'm not sure this is right. help!!!
