Calculate the torsion frequency of this blade using Rayleigh-Ritz method. Assume one term in the deflection series, the strain energy equation, and the kinetic energy equation as given.

I got \(\omega = \sqrt{\frac{3GJ+I_{\theta}\Omega^2R^2}{I_{\theta}R^2}}\). Work is attached. Attachments:RayleighRitz.pdf (487.96 KB)

I think there's a typo between what you wrote here and your answer on the PDF. I believe the R in the denominator should be squared. Otherwise, we have the same answer!
