Torque (Moment of Force)

Torque measures the tendency of a force to cause rotation about an axis.

Formula

tau = F * r * sin(theta)

Maximum torque occurs when the force is perpendicular to the lever arm (theta = 90 degrees).

Exemple Résolu

A 50 N force is applied perpendicular to a 0.3 m wrench.

  1. tau = F * r * sin(theta)
  2. tau = 50 * 0.3 * sin(90°)
  3. tau = 50 * 0.3 * 1
  4. tau = 15 N·m
