Rotational Motion Self Test: Moment of Inertia

Moment of Inertia

Moment of inertia is the rotational analogue to mass.

 Here is a list of moments of inertia for various bodies:
slender rod: axis through center I = (1/12)ML
axis through end I = (1/3)ML
rectangular plane: axis through center I = (1/12)M(a + b)
axis along edge I = (1/3)Ma
cylinder hollow I = (1/2)M(R1 + R2)
solid I = (1/2)MR
thin-walled hollow I = MR
sphere solid I = (2/5)MR
thin-walled hollow I = (2/3)MR
