Frequently asked questions
What's the formula?
τ = F × r × sin(θ).
What happens at 90 degrees?
The sine equals 1, so torque is at its maximum for that force and distance.
What unit returns?
Newton-meter, N·m.
What's the lever arm?
It is the distance from the turning axis to the point where the force acts.
