How to calculate wheel torque from engine torque Wheel torque can be calculated function of engine torque if the parameters and status of the transmission are known. In this tutorial, we are going to calculate the wheel torque and force for a given: Drive shaft Design, key and Keyways. Key dimensions: Parallel keys are most commonly used. The key and key seat cross section are ISO standardized. The key length should be less than about 1.5 times the shaft diameter to ensure a good load distribution over the entire key length when the shaft becomes twisted when loaded in torsion.
