This formula uses 5 Variables
Variables Used
Wheel Force Function - (Measured in Newton) - A Wheel Force Function is the total force generated by each wheel on a drive train due to its rotation and friction between the traction line.
Gear Ratio of Transmission - Gear Ratio of Transmission is the ratio between the revolutions of the engine crankshaft and the revolutions of the shaft which comes out of the gearbox.
Gear Ratio of Final Drive - Gear Ratio of Final Drive is the ratio between the revolutions of the gearbox shaft and the revolutions of the wheels.
Engine Torque - (Measured in Newton Meter) - Engine Torque is defined as the torque generated by the motor of a vehicle.
Radius of Wheel - (Measured in Meter) - The Radius of Wheel is any of the line segments from its center to its perimeter, and in more modern usage, it is also their length.
STEP 1: Convert Input(s) to Base Unit
Gear Ratio of Transmission: 2.55 --> No Conversion Required
Gear Ratio of Final Drive: 2 --> No Conversion Required
Engine Torque: 4 Newton Meter --> 4 Newton Meter No Conversion Required
Radius of Wheel: 1.89 Meter --> 1.89 Meter No Conversion Required
STEP 2: Evaluate Formula

On what parameters torque available at wheel of any automobile is dependent on?

The torque available at wheel of any automobile is dependent on 2 parameters namely:
1.Engine torque
2.Gear ratio
The engine torque may be obtained from engine manufacturer. But you are less likely to get a full torque curve. But you will most likely have max torque at a certain engine speed (since they put it in vehicle specs).
For gear ratio, it is ratio of engine rotation to corresponding wheel rotations.

How to Calculate Wheel Force Function?

Wheel Force Function calculator uses Wheel Force Function = (Gear Ratio of Transmission*Gear Ratio of Final Drive*Engine Torque)/(2*Radius of Wheel) to calculate the Wheel Force Function, The Wheel Force Function is defined as the total force generated by each wheel on a drive train due to its rotation and friction between the traction line.
