Torque Calculator (with Lever Arm)
Compute the torque exerted by a force applied at a distance from the pivot point. Enter the force and perpendicular lever arm distance to calculate torque.
What this calculator is doing
Torque (also known as moment or turning force) is the rotational equivalent of linear force. It is calculated using the following formula:
\[ \tau = F \cdot r \cdot \sin(\theta) \]
Where:
\( \tau \) = Torque (Newton-meters, Nm)
\( F \) = Applied Force (Newtons, N)
\( r \) = Lever arm length (meters, m)
\( \theta \) = Angle between the force and lever arm (degrees)
In most basic cases where the force is applied perpendicular to the lever arm, \( \theta = 90^\circ \) and \( \sin(\theta) = 1 \), so the equation simplifies to:
\[ \tau = F \cdot r \]
This calculator assumes a perpendicular force unless you specify an angle.
