Torque Calculator
Solve arbitrary-angle torque, audit planar force and moment equilibrium, or calculate reactions for a simply supported beam with point loads.
Calculator
Formula
τ = rF sinθ; ΣFx = 0; ΣFy = 0; ΣM = 0
- τ — Torque
- N·m
- F — Perpendicular force
- N
- r — Lever arm
- m · cm · km
Assumptions and limits
- Counter-clockwise torque is positive; beam loads are downward non-negative magnitudes.

Frequently asked questions
Are my inputs uploaded?
No. This calculator runs locally in your browser. Inputs are placed in a URL only when you explicitly copy a share link.
Why are units converted first?
Canonical units prevent scale errors when inputs use mixed units. The result is converted back to your selected output unit afterward.
Does the result replace professional judgment?
No. The result applies only to the stated model and assumptions. Qualified people should review high-risk engineering, medical, or laboratory decisions.
