How to use Torque and Lever Balance Calculator
Torque magnitude is arm times force times sine of the included angle. Perpendicular static balance equates opposing force-arm products; the second arm must be positive.
- Enter first lever arm (m), first force magnitude (n), included angle (degrees), opposing lever arm (m).
- Choose the stated convention and check the units and supported model.
- Calculate, inspect the result, then copy or download it.
Good to know
- Meters,newtons,newton-meters; nonnegative force, positive arms and angle0–180degrees. Magnitudes only; no tightening, rigging or structural certification.
- Runs locally. Text/JSON fields are capped at30,000 characters; stricter page-specific and numeric-string limits also apply. Numeric inputs are bounded to magnitude1e15 and nonzero magnitude at least1e-100 unless an exact-string mode states otherwise. Approximate summaries use12 significant digits; CSV numeric cells retain the complete stored value and potentially formula-like string cells gain a protective apostrophe; unsupported, non-finite or detected underflow states return an error.
Common questions
What does the balance mode assume about force direction?
Both forces act perpendicularly to their respective arms and produce opposing moments around the same ideal pivot.
Is the input uploaded or saved?
No. The tool calculates inside this browser tab and provides a local download; it does not persist your input.
