โFrequently Asked Questions
What is torque?
Torque (ฯ) is the rotational equivalent of force, measuring the turning effect. Calculated as ฯ = r ร F, where r is the distance from the axis of rotation and F is the applied force. Measured in Newton-meters (Nยทm). Greater distance or force creates more torque.
Why is torque important?
Torque determines an object's angular acceleration (rotation). Engines, motors, and tools are rated by torque output. Opening a door, turning a bolt, or spinning a wheel all require torque. Higher torque means more rotational power and ability to overcome resistance.
What's the difference between torque and force?
Force causes linear acceleration (straight-line motion). Torque causes angular acceleration (rotational motion). Force is measured in Newtons; torque in Newton-meters. Torque depends on both force magnitude and where it's applied (distance from pivot).
Why do longer wrenches make it easier?
Torque equals force times distance: ฯ = rF. A longer wrench (larger r) produces more torque with the same force. If you double the wrench length, you need half the force for the same torque. This is mechanical advantage through leverage.
What's the difference between torque and horsepower?
Torque is rotational force (how hard the engine pushes). Horsepower is power (how fast it does work). They're related: HP = (Torque ร RPM) / 5252. High torque at low RPM is good for acceleration; horsepower determines top speed. Sports cars prioritize HP, trucks prioritize torque.
Can torque be negative?
Yes! Torque direction depends on rotation. Clockwise is typically negative, counterclockwise positive (or vice versa by convention). When balanced torques cancel (ฮฃฯ = 0), objects don't rotate - this is rotational equilibrium, crucial in statics and engineering.
