μ = Hc/(w*n)
This formula uses 4 Variables
Variables Used
Coefficient of Friction for Locomotive - Coefficient of Friction for Locomotive between the driving wheels and the rails depends largely upon the two factors called condition of the rail surface and speed of the locomotive.
Hauling Capacity of a Locomotive - (Measured in Tonne) - Hauling Capacity of a Locomotive is the maximum amount of weight that can be filled and carried beyond regular capacity.
Weight on Driving Axle - (Measured in Tonne) - Weight on Driving Axle is the weight transmitted by several wheels attached to that axle to the surface on which the locomotive rests.
No of Pairs of Driving Wheels - No of Pairs of Driving Wheels in train usually vary from 260 to 800.These driving wheels are driven by traction motor.
STEP 1: Convert Input(s) to Base Unit
Hauling Capacity of a Locomotive: 12 Tonne --> 12 Tonne No Conversion Required
Weight on Driving Axle: 20 Tonne --> 20 Tonne No Conversion Required
No of Pairs of Driving Wheels: 3 --> No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
μ = Hc/(w*n) --> 12/(20*3)
Evaluating ... ...
μ = 0.2
STEP 3: Convert Result to Output's Unit
0.2 --> No Conversion Required
FINAL ANSWER
0.2 <-- Coefficient of Friction for Locomotive
(Calculation completed in 00.004 seconds)
