Question

Quizplus · Accepted Answer

The equilibrium super elevation in railway engineering, given the units for G (gauge in meters), V (speed of trains in km/hour), and R (radius of the curve in meters), is correctly represented by the formula GV²/127R. This formula is used to calculate the necessary super elevation (or banking of the track) to counteract the centrifugal force acting on a train moving through a curve, ensuring that the train remains balanced and does not derail. The number 127 comes from the unit conversions and constants used in the physics of circular motion.
