Fα = (277.8*We*α)+(W*Rsp)
This formula uses 5 Variables
Variables Used
Acceleration Tractive Effort - (Measured in Newton) - Acceleration Tractive effort to the force exerted by a locomotive or a vehicle's driving wheels on the track, which is necessary to overcome the resistance and accelerate the vehicle forward.
Accelerating Weight of Train - (Measured in Kilogram) - Accelerating Weight of Train is the effective weight of train that has angular acceleration due to the rotational inertia including the dead weight of the train.
Acceleration of Train - (Measured in Meter per Square Second) - Acceleration of Train is the rate of change in velocity to the change in time.
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.
STEP 1: Convert Input(s) to Base Unit
Accelerating Weight of Train: 33000 Ton (Assay) (US) --> 962.500110009752 Kilogram (Check conversion ​here)
Acceleration of Train: 14.4 Kilometer per Hour Second --> 4.0000000000032 Meter per Square Second (Check conversion ​here)
Weight of Train: 30000 Ton (Assay) (US) --> 875.000100008866 Kilogram (Check conversion ​here)
Specific Resistance Train: 9.2 --> No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
Fα = (277.8*We*α)+(W*Rsp) --> (277.8*962.500110009752*4.0000000000032)+(875.000100008866*9.2)
Evaluating ... ...
Fα = 1077580.12316377
STEP 3: Convert Result to Output's Unit
1077580.12316377 Newton --> No Conversion Required
FINAL ANSWER
1077580.12316377 1.1E+6 Newton <-- Acceleration Tractive Effort
