Calculation Formula

Force (F) = Torque (τ) / Radius (r)

Where:
F is the force required in Newtons
τ is the torque in Newton-meters
r is the radius in meters

How to Use the Calculator

  1. Enter the torque applied to the key in Newton-meters.
  2. Enter the radius of the key in meters.
  3. Click the "Calculate" button to determine the force required.
  4. The result will be displayed in Newtons.

Understanding the Formula

The force required to turn a key in a lock can be calculated using the formula:

Force (F) = Torque (τ) / Radius (r)

This formula shows that the force is inversely proportional to the radius. A smaller radius will require more force to produce the same torque.
