Understanding Shaft Torque

Torque on a shaft is calculated as the product of force and the distance from the point of rotation. This calculator uses the formula: T = F × r, where T is torque in Newton-meters (Nm), F is force in Newtons (N), and r is the radius in meters (m).

Applications

This calculator is useful for engineers and technicians working with rotating machinery, such as in automotive, aerospace, and industrial applications. It helps determine the torque requirements for shafts, gears, and other rotating components.
