Torque
45.00 N·m

Calculation steps

  1. 1τ = r × F × sinθ = 0.3 × 150 × sin(90°)
  2. 2sin(90°) = 1.0000
  3. 3τ = 45.00 N·m

Typical torque reference

20–60 N·mPower screwdriver / bike
100–150 N·mCar lug wrench
150–350 N·mPassenger car engine
400–700 N·mPerformance / diesel
1000+ N·mHeavy trucks / machinery
Power = torque × angular velocity: for the same power, lower RPM means higher torque — that is what gearboxes trade. At 90° the full force contributes to torque; pushing along the lever (0°) produces zero torque. Diesel engines make torque at low RPM; EVs deliver max torque from 0 RPM, which is why they launch so hard.
