Struct RotatingBody 

pub struct RotatingBody {
    pub moment_of_inertia: f64,
    pub angular_velocity: f64,
}

A rotating body with scalar moment of inertia and angular velocity.

Fields

moment_of_inertia: f64

angular_velocity: f64

Implementations

impl RotatingBody

pub const fn new( moment_of_inertia: f64, angular_velocity: f64, ) -> Option<RotatingBody>

Creates a rotating body when moment_of_inertia is non-negative and both values are finite.

pub fn angular_momentum(&self) -> Option<f64>

Computes angular momentum using L = Iω.

pub fn rotational_kinetic_energy(&self) -> Option<f64>

Computes rotational kinetic energy using KE_rot = 0.5 * I * ω².

Examples

use use_rotation::RotatingBody;

let body = RotatingBody::new(4.0, 5.0).unwrap();

assert_eq!(body.rotational_kinetic_energy(), Some(50.0));

pub fn angular_acceleration_from_torque(&self, torque: f64) -> Option<f64>

Computes angular acceleration from applied torque using α = τ / I.

Trait Implementations

impl Clone for RotatingBody

fn clone(&self) -> RotatingBody

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for RotatingBody

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl PartialEq for RotatingBody

fn eq(&self, other: &RotatingBody) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
