Function torque_kernel 

pub fn torque_kernel(
    radius: &CausalMultiVector<f64>,
    force: &CausalMultiVector<f64>,
) -> Result<PhysicalVector, PhysicsError>

Calculates torque as the outer product of radius and force: $\tau = r \wedge F$.

In Geometric Algebra, torque is a bivector representing the plane of rotation.

Arguments

• radius - Position vector from pivot.
• force - Force vector applied.

Returns

• Result<PhysicalVector, PhysicsError> - The torque bivector wrapped in a physical vector.
