Torque responds to either a longer arm or a larger force. Exact arithmetic here means exact results for the stated model inputs; measured inputs still carry uncertainty and significant-figure limits.

Base arm-force product

Lever arm 3 m times force 4 N gives torque 12 newton meters.

τ=3×4=12\tau=3\times4=12
Torque arm force rowLever arm and force multiply to make torque.r=3 mF=4 Nr=3 mF=4 Ntau=12 N*m

Longer arm doubles torque

Lever arm 6 m times force 4 N gives torque 24 newton meters.

τ=6×4=24\tau=6\times4=24
Torque arm force rowLever arm and force multiply to make torque.r=6 mF=4 Nr=6 mF=4 Ntau=24 N*m

Larger force also doubles torque

Lever arm 3 m times force 8 N gives torque 24 newton meters.

τ=3×8=24\tau=3\times8=24
Torque arm force rowLever arm and force multiply to make torque.r=3 mF=8 Nr=3 mF=8 Ntau=24 N*m
