I agree, and I also now understand that my experiment was finding k at the centre of mass but the original formula I was using to find theoretical k (k^2 = (L^2) / 3) is to find k at the end of the bar. k^2 = (L^2)/12 finds k at the centre of mass and this is what i wanted. The two are...

Oh dear! Well that's what it is then, works perfectly now - thank you so much! Ps, tau is the letter representing time period in the textbooks/refs I've been using...

I'm having some trouble prooving a basic compound pendulum theory - my company makes a piece of kit designed to do just that. In a simple experiment involving a long thin bar which is set on a knife edge and allowed to swing freely I have been changing the length of the bar and measuring the...
