I have built a model of rotating blades of a helicopter and want to mathematically calculate it's moment of inertia. I am unsure on how to do that.(adsbygoogle = window.adsbygoogle || []).push({});

Its a simple model:

a square wooden base with uniform thickness and 4 equally long blades made of styrofoam from the midpoints of the 4 sides of the square.

The rotational axis is through the centre of the square

Lets just say i know the density, mass and thickness of the base and the blades, how do i get moment of inertia for a specific length of blades ?

Thank you
