Function solid_sphere_moment_of_inertia
pub fn solid_sphere_moment_of_inertia(mass: f64, radius: f64) -> Option<f64>Expand description
Computes solid-sphere moment of inertia using I = (2 / 5)mr².
Returns None when mass or radius is negative, when any input is not finite, or when the
computed moment of inertia is not finite.
