This formula uses 3 Variables

Variables Used

Coefficient of Adhesion - Coefficient of Adhesion is defined as the ratio of the tractive effort required to propel the wheel of a locomotive to its adhesive weight.
Tractive Effort - (Measured in Newton) - Tractive Effort, the term tractive force can either refer to the total traction a vehicle exerts on a surface, or the amount of the total traction that is parallel to the direction of motion.
Weight of Train - (Measured in Kilogram) - Weight of Train is total weight of the train in tonns.

STEP 1: Convert Input(s) to Base Unit

Tractive Effort: 545 Newton --> 545 Newton No Conversion Required
Weight of Train: 30000 Ton (Assay) (US) --> 875.000100008866 Kilogram (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

μ = F_t/W --> 545/875.000100008866

Evaluating ... ...

μ = 0.622857071667166

STEP 3: Convert Result to Output's Unit

0.622857071667166 --> No Conversion Required

FINAL ANSWER

0.622857071667166 ≈ 0.622857 <-- Coefficient of Adhesion
