Calculation of tractive effort
WebTractive Effort. Definition: Tractive effort is defined as the force at the rims or the outer edges of the driving wheels of moving trains. In other words, it is the sum of the tractive … WebTo calculate the power required to overcome the tractive effort of a vehicle, we can use the following equation: Power = Tractive Effort x Vehicle Speed The tractive effort is given by: Tractive Effort = (Vehicle Weight x Grade Resistance) + (0.5 x Cd x Af x Air Density x Vehicle Speed^2) View the full answer Step 2/2 Final answer
