I = m(r1^2 + r2^2)/2
Comes from I = mk^2
Where k, radius of gyration = (0.5(r1^2 + r2^2))^0.5
and m is the mass of the component.
Is this not correct?
The calculated value also agrees with the output from the CAD model. I'm having difficulty getting consistent results from the physical...
I need to measure the moment of Inertia of a 20mm dianeter rotor. I have calculated the inertia at 3500gmm^2 using the following equation to sum the components (cylinders):
Inertia, I = m(r1^2 + r2^2)/2
I've measured it by timing it rolling down a slope:
Inertia, I = mgr^2t^2Sinq/2L - mr^2...
