Tractive Effort Required while going down Gradient Solution

STEP 0: Pre-Calculation Summary

Formula Used

Down Gradient Tractive Effort = (Weight of Train*Specific Resistance Train)-(98.1*Weight of Train*Gradient)
F_down = (W*R_sp)-(98.1*W*G)
This formula uses 4 Variables

Variables Used

Down Gradient Tractive Effort - (Measured in Newton) - Down Gradient Tractive Effort a vehicle is moving down a gradient, the tractive effort required to maintain its speed or slow down is reduced force of gravity in the same direction.
Weight of Train - (Measured in Kilogram) - Weight of Train is total weight of the train in tonns.
Specific Resistance Train - Specific Resistance Train is defined in terms of force required to encounter resistance arising due to vehicle, track, grade, curve, acceleration, wind at different time and place etc.
Gradient - The Gradient is simply the product of the sine angle and constant 100 for the train. It is expressed in the percentage of the rise in meters in the track distance of 100 metres.

STEP 1: Convert Input(s) to Base Unit

Weight of Train: 30000 Ton (Assay) (US) --> 875.000100008866 Kilogram (Check conversion here)
Specific Resistance Train: 9.2 --> No Conversion Required
Gradient: 0.52 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

F_down = (W*R_sp)-(98.1*W*G) --> (875.000100008866*9.2)-(98.1*875.000100008866*0.52)

Evaluating ... ...

F_down = -36585.5041815707

STEP 3: Convert Result to Output's Unit

-36585.5041815707 Newton --> No Conversion Required

FINAL ANSWER

-36585.5041815707 ≈ -36585.504182 Newton <-- Down Gradient Tractive Effort
