Mechanical Torque, Force & Lever Arm Physics Calculator (τ = F × r × sin(θ))
Calculate rotational torque (τ) in Newton-meters (N·m) and Foot-Pounds (ft-lb), applied force, lever arm distance, and mechanical horsepower (HP) from RPM.
Calculator Inputs
Live Real-TimeCalculated Torque (N·m)
Torque in Foot-Pounds (ft·lb)
44.25 ft·lb
Mechanical Horsepower (HP)
16.85 HP
Power in Kilowatts (kW)
12.57 kW
Mechanical Principle: Doubling the lever arm length doubles generated torque by 100% with the exact same applied force.
Torque & Horsepower Breakdown
Detailed Calculation Breakdown
Calculation Methodology
Torque: τ = F * r * sin(θ). At perpendicular 90°: τ = F * r. Mechanical Power (W) = (Torque * 2π * RPM) / 60. Horsepower (HP) = Power (W) / 745.7.
