Category:Huygens-Steiner Theorem

This category contains pages concerning Huygens-Steiner Theorem:

Let $B$ be a body of mass $M$.

Let $I_0$ be the moment of inertia of $B$ about some axis $A$ through the centre of mass of $B$.

Let $I$ the moment of inertia of $B$ about another axis $A'$ parallel to $A$.

Then $I_0$ and $I$ are related by:

$I = I_0 + M l^2$

where $l$ is the perpendicular distance between $A$ and $A'$.
