# Load Torque Calculator, Formula, Load Torque Calculation

## Load Torque Calculator:

Enter the values of mass load, ML(kg) and radius of the pulley, RP(m) to determine the value of the load torque, LT(N.m).

 Enter Mass Load: kg Enter Radius of the Pulley: m Result – Load Torque: N.m

## Load Torque Formula:

Load Torque, LT(N.m) is a critical parameter in mechanical and electrical engineering, referring to the torque required to drive a load, such as a gear, pulley, or wheel. It is a measure of the rotational force necessary to overcome the inertia and friction of the load, ensuring its motion at a desired speed or maintaining a specific position.

Load Torque, LT(N.m) in Newton metres is equal the product of mass load, ML(kg) in kilogram and radius of the pulley, RP(m) in metres.

Load Torque, LT(N.m) = ML(kg) * RP(m)

LT(N.m) = Load torque in Newton metres, N.m.

ML(kg) = Mass load in kilogram, kg.

RP(m) = radius of the pulley in metres,

An elevator has a mass load (ML) of 800 kg. The radius of the pulley system (RP) used to lift the elevator is 0.5 meters. Determine the Load torque generated.

Given: ML(kg) = 800kg, RP(m) = 0.5m.

Load Torque, LT(N.m) = ML(kg) * RP(m)

LT(N.m) = 800 * 0.5

LT(N.m) = 400N.m

1. The load torque required for a certain application is 250 Nm. The mass load (ML) being moved or supported is 1000 kg and find the radius of the pulley.

Given: ML(kg) = 1000kg, LT(N.m) = 250N.m.

Load Torque, LT(N.m) = ML(kg) * RP(m)

RP(m) = LT(N.m) / ML(kg)

RP(m) = 250 / 1000

RP(m) = 0.25m
