Frequently asked questions
- What is torque?
- Torque is the rotational equivalent of force, measured in newton-meters (N·m), calculated as force times lever arm distance times the sine of the angle between them.
- What angle gives maximum torque?
- Torque is maximized at a 90° angle between the force and the lever arm, since sin(90°) = 1.
- Why might solving for angle return no result?
- If the required sine value falls outside -1 to 1, no valid angle exists for those inputs — check your numbers.
