Parallel Axis Theorem
Parallel axis theorem adds term:
Select the correct option:
Solution
Md2
The Parallel Axis Theorem allows us to find the moment of inertia I of a body about any axis, provided we know its moment of inertia Icm about a parallel axis passing through its center of mass: I=Icm+Md2 where:
- M: total mass of the body
- d: perpendicular distance between the two parallel axes.
