How the torque calculator works
Torque peaks when force is applied perpendicular to the lever arm — at 90 degrees, sin(θ) equals one.
Formula
τ = F × r × sin(θ)
Worked example
250 N on a 0.4 m wrench at 90° produces 100 N·m.
Frequently asked questions
Why does a longer wrench help?
Torque scales linearly with lever length, so doubling the handle doubles the torque.
