Struct Moments

pub struct Moments {
    pub moment_x: f64,

    pub moment_yy: f64,

Expand description

A collect of moment integrals for a path, used for computing shape properties like area, centroid, and inertia.

The moments are computed using Green’s theorem, which relates the integrals of a function over a closed curve to the integrals of its partial derivatives over the region enclosed by the curve.

Fields§

§moment_x: f64

The first moment of area about the x-axis.

§moment_y: f64

The first moment of area about the y-axis.

§moment_xx: f64

The second moment of area about the x-axis (also known as the area moment of inertia about the x-axis).

§moment_xy: f64

The second moment of area about the xy-axis (also known as the product of inertia).

§moment_yy: f64

The second moment of area about the y-axis (also known as the area moment of inertia about the y-axis).

where T: Any,

§

fn into_any(self: Box<T>) -> Box<dyn Any>

Convert Box<dyn Trait> (where Trait: Downcast) to Box<dyn Any>. Box<dyn Any> can then be further downcast into Box<ConcreteType> where ConcreteType implements Trait.
