# Torque

vCalc.Torque

The **Torque** calculator computes torque as a function of force (**F**) and perpendicular distance (**L**).

**INSTRUCTIONS:** Choose the preferred units and enter the following:

- (
**F**) This is the force. - (
**L**) This is the perpendicular distance.

**Torque (τ):** The torque is returned in N•m. However, this can be converted to compatible units via the pull-down menu.

### General Information

The formula for the magnitude of torque (τ), the quantitative measure of the tendency force to cause rotational motion of a body. The inputs are Force (`F`) and the distance (L) between the pivot point and the point where the force is applied. L is measured by the perpendicular distance from the pivot point, P, to the line of force.

Standard SI units are Force in newtons and r in meters. The units of torque match the units of the input force (`F`) times the units of the distance (l).

Since torque is a measure of force causing a rotation about a specific point, the torque can be both positive (causing counter-clockwise rotation) or negative (causing clockwise rotation).

In the picture, the force, `vecF`, will cause a counter-clockwise rotation about the pivot point, P. The magnitude of the force will be defined by `tau` = `vecF * L`.
