Engine Torque Calculator:

Enter the values of Force exerted by the engine in Newton and the crankshaft’s radius in meters to calculate the Engine Torque in Newton metre.

Engine Torque Formula:

Engine torque refers to the twisting force produced by an engine, crucial for understanding a vehicle’s acceleration and towing capacity. It directly affects how a vehicle performs under various driving conditions.

Torque, T_e(N.m) in Newton meters, is calculated by multiplying the force exerted by the engine, F_e(N) with the crankshaft’s radius or distance from the axis of rotation, D_c(N.m).

Torque, T_e(N.m) = F_e(N) * D_c(N.m).

T_e(N.m) = Torque in Newton metres, N.m.

F_e(N) = Force exerted by the engine in Newton, N.

D_c(N.m)  = the crankshaft’s radius in meters, m.

Engine Torque Calculation:

1. If an engine exerts a force of 500N and the crankshaft’s radius is 0.05 meters, calculate the torque produced by the engine.

Given: F_e(N) = 500N,  D_c(N.m) = 0.05m.

Torque, T_e(N.m) = F_e(N) * D_c(N.m).

T_e(N.m) = 500 * 0.05

T_e(N.m) = 25N.m.

2. An engine torque is 45 Newton metre, and the distance from the crankshaft’s axis of rotation is 0.06 meters. Determine the engine force applied.

Given: T_e(N.m) = 45N,  D_c(N.m) = 0.06m.

Torque, T_e(N.m) = F_e(N) * D_c(N.m).

45 = F_e(N) * 0.06

F_e(N) = 750N.
