The rotational equivalent of force — how effectively a push creates a twist.
A force applied perpendicular to the lever arm (90°) produces maximum torque; a force applied along the lever arm's own direction (0°) produces zero torque, regardless of how strong it is — this is why door handles are placed far from the hinge.
Wrenches, car engines, and door hinges are all governed by this formula — a longer wrench handle multiplies the torque you can apply with the same hand force, which is why breaker bars are longer than standard wrenches.
Torque (N·m)
6
τ = F · r · sin(θ)
What you entered
τ = F × r × sin(θ)
20 × 0.3 × sin(90°)= 6 N·mResult
Torque (N·m): 6
A 20N force at a 0.3m lever arm produces 6 N·m of torque.
