Understanding Torque
The Rotational Force
Learn About TorqueTorque is the rotational equivalent of force—it measures how much a force causes an object to rotate around an axis. Understanding torque is essential for mechanics, engineering, and everyday tasks like tightening bolts.
Torque vs Power
| Aspect | Torque | Power |
|---|---|---|
| Measures | Rotational force | Work over time |
| Units | N·m, ft·lb | Watts, HP |
| Effect | Ability to turn | Speed of work |
| Analogy | Push strength | Sustained speed |
Power = Torque × Angular velocity
Conclusion
Torque describes rotational force and depends on both force magnitude and the distance from the rotation axis. Longer lever arms multiply torque. In vehicles, torque determines acceleration ability while power determines top speed. Both work together in mechanical systems.
