Tractive Effort at Wheel Solution

STEP 0: Pre-Calculation Summary

Formula Used

Wheel Tractive Effort = (Pinion Edge Tractive Effort*Diameter of Pinion 2)/Diameter of Wheel
F_w = (F_pin*d₂)/d
This formula uses 4 Variables

Variables Used

Wheel Tractive Effort - (Measured in Newton) - Wheel tractive effort refers to the force that a locomotive or a vehicle's drive wheels apply to the track or the road to propel the vehicle forward.
Pinion Edge Tractive Effort - (Measured in Newton) - Pinion Edge Tractive Effort is the effective force acting on the wheel of the locomotive, necessary to propel the train.
Diameter of Pinion 2 - (Measured in Meter) - Diameter of Pinion 2 is known as when two gears run together, the one with the smaller number of teeth is called the pinion and its diameter is pinion diameter.
Diameter of Wheel - (Measured in Meter) - Diameter of wheel is the length of the wheel (diameter) of the train.

STEP 1: Convert Input(s) to Base Unit

Pinion Edge Tractive Effort: 64 Newton --> 64 Newton No Conversion Required
Diameter of Pinion 2: 0.8 Meter --> 0.8 Meter No Conversion Required
Diameter of Wheel: 1.55 Meter --> 1.55 Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

F_w = (F_pin*d₂)/d --> (64*0.8)/1.55

Evaluating ... ...

F_w = 33.0322580645161

STEP 3: Convert Result to Output's Unit

33.0322580645161 Newton --> No Conversion Required

FINAL ANSWER

33.0322580645161 ≈ 33.03226 Newton <-- Wheel Tractive Effort
