How it works
Use force torque with the units stated beside the fields. This form solves for force magnitude; enter the known quantities in Torque magnitude, Radius, Acute angle.
Inputs and units
| Input | Example value | What to enter |
|---|---|---|
| Torque magnitude | 4.5 N·m | Formula symbol: τ. Required unit: N·m. Must be greater than zero. |
| Radius | 2.25 m | Formula symbol: r. Required unit: m. Distance from the centre to the edge; half the diameter. Must be greater than zero. |
| Acute angle | 22.5 ° | Formula symbol: θ. Required unit: °. Must be greater than zero. Allowed range: 1E-9–89.999999. |

Questions and answers
Can I use the example values for my own calculation?
The example values illustrate the calculation. Replace every input with your own information, especially dates, rates and the selected operation.
When can I use the force magnitude result?
This model uses positive magnitudes. Radius runs from the axis to the force application point. Angle is between radius and force; only the acute branch is solved.
Why are some results rounded?
Results display up to 8 decimal places. Calculations use the unrounded values; very small values use scientific notation. JavaScript floating-point arithmetic can introduce tiny rounding differences.
Are my inputs sent to a server?
The calculator processes inputs in your browser. Its code does not send your values to a server.
