Understanding Moment of Force (Torque)

Moment of force, commonly termed torque ($\vec{\tau}$), measures the rotational effectiveness of a force applied at a perpendicular distance from a pivot axis: $\vec{\tau} = \vec{r} \times \vec{F}$. Measured in Newton-meters ($\text{N}\cdot\text{m}$) in SI, and pound-force feet ($\text{lbf}\cdot\text{ft}$) or pound-force inches ($\text{lbf}\cdot\text{in}$) in Imperial ($1\text{ lbf}\cdot\text{ft} \approx 1.355818\text{ N}\cdot\text{m}$). Critical for engine output and structural bolting specifications.
