Torque Formula
Basic Formula
τ = F × r × sin(θ)
Where:
- • τ = torque (N⋅m)
- • F = force (N)
- • r = lever arm (m)
- • θ = angle between force and lever
Perpendicular Force
τ = F × r
When force is perpendicular (θ = 90°)
Common Torques
- • Car engine: 200-500 N⋅m
- • Bicycle pedal: 40-100 N⋅m
- • Door handle: 2-5 N⋅m
