## 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).

Maximum torque occurs when the force is perpendicular to the lever arm (theta = 90 degrees).
计算示例
A 50 N force is applied perpendicular to a 0.3 m wrench.
- tau = F * r * sin(theta)
- tau = 50 * 0.3 * sin(90°)
- tau = 50 * 0.3 * 1
- tau = 15 N·m
