Which one of the curves below represents a road gradient of 10%, if the mass of the vehicle is 1 ton?(a) B(b) A(c) D(d) CI got this question during an interview.This is a very interesting question from Vehicles and Powertrain topic in portion Emission Control Methods, Electric & Conventional Vehicles of Automobile Engineering
Answer» The correct OPTION is (a) B The best explanation: Fgradient = mvehicle * g * SIN (α). For SMALL angles α, sin (α) = α = G. At G = 10%, sin (α) = 0.1 = α. Hence Fgradient = 1000 * 9.81 * 0.1 = 981 N. Using G = 0% curve as base curve and at speed = 0 Kmph, curve B is higher than the G = 0% curve across the full speed RANGE.
