WebThe equation for Tractive Effort is c P (d)^2 s TE = ----- D TE = tractive effort in lbs c = a constant determined by the mean effective pressure and friction (usually 85%) P = boiler … WebThe Tractive Effort at wheel formula is defined as the ratio of the product of tractive effort at the edge of pinion & diameter of opinion to the diameter of the wheel and is represented as Ftrain = (FP*d2)/d or Tractive Effort on Train = (Tractive Effort at Edge of Pinion*Diameter of Pinion 2)/Diameter of Wheel.
WebTo map out our tractive effort for 1st gear we simple take our torque and multiply it by the total gear ratio for 1st: 3:1 (Gear) * 4:1 (Final) = 12:1, and scale the resulting graph to go between 10km/h (at 1000rpm) and 50km/h (which is 5000rpm). Our peak torque at the engine is 340lb/ft at 3000rpm, and our peak axle torque in 1st will be 12 ...
