19.1.4 momentForPoly

inertia = physics.misc.momentForPoly(mass, vertices, offset)

Parameter

Type

Description

mass

in number

The mass of the polygon

vertices

in {physics.Vect}

A list of vertices defining the shape of the polygon

offset

in physics.Vect

The offset of the polygon from the center of gravity

inertia

out number

The inertia of the polygon


This routine computes the moment of inertia for a polygon. This is a useful helper routine for computing the moment of inertia as an input to the physics.Body(...) constructor.
