Thanks Tiny-Tim! I really appreciate it. I'll give it a go and see what I can get.

Hi Guys, I was hoping someone would be able to help me with this integration. It's been killing me haha. I've got this energy balance equation: mgh = 0.5m(v^2) + 0.5I(w^2) + T(theta) Basically, It's a gravitational potential energy that is converted to a velocity of a falling object...

I've worked it out, Thanks for your help. Turns out we needed to estimate the mass from density and it's dimensions. Made it a lot easier haha.

Ah sorry, I want to find it for the shaft that the string is wound around. I can eliminate omega since it's a common term through gear ratios etc. It's just those moments of Inertia for each flywheel that's killing me.

Hi Guys, I'm having trouble finding the equivalent moment of inertia for a system. Basically it's a mass attached to a string, which is attached to a shaft. As the mass drops, the string unravels imparting some rotation on the shaft, this shaft rotates a small flywheel, and also rotates a...
