Struct CompositeShape 

pub struct CompositeShape {
    pub shapes: Vec<(i8, StructuralShape)>,
}

A composite composed of multiple individual shapes

let x = CompositeShape::new()
    .add(StructuralShape::new_rod(2.0).with_cog(2.0, 0.0))
    .add(StructuralShape::new_rod(2.0).with_cog(-2.0, 0.0));

Fields

shapes: Vec<(i8, StructuralShape)>

Constituent shapes

Implementations

impl CompositeShape

pub fn new() -> Self

This creates a new composite shape, identical to default

pub fn add(&mut self, new_shape: StructuralShape) -> Self

This function adds a new shape to the composite

pub fn sub(&mut self, new_shape: StructuralShape) -> Self

This function subtracts a new shape to the composite

pub fn calculate_cog(&self) -> (Length, Length)

Calculate center of gravity and update COG of members

pub fn update_cog(&mut self)

Shift structure to have cog at (0.0,0.0)

pub fn moi_x(&self) -> Quantity<ISQ<P4, Z0, Z0, Z0, Z0, Z0, Z0>, SI<f64>, f64>

This function returns the moment of inertia of the composite shape around the x-axis

pub fn moi_y(&self) -> Quantity<ISQ<P4, Z0, Z0, Z0, Z0, Z0, Z0>, SI<f64>, f64>

This function returns the moment of inertia of the composite shape around the y-axis

pub fn polar_moi( &self, ) -> Quantity<ISQ<P4, Z0, Z0, Z0, Z0, Z0, Z0>, SI<f64>, f64>

This function returns the polar moment of inertia of the composite shape around the origin.

pub fn area(&self) -> Area

This function returns the area of the composite shape
