Function rod_moment_of_inertia_about_end
pub fn rod_moment_of_inertia_about_end(mass: f64, length: f64) -> Option<f64>Expand description
Computes the moment of inertia of a uniform rod about one end.
Formula: I = (1 / 3) * m * L²
Returns None when mass or length is negative, when either input is not finite, or when
the computed result is not finite.
