Web6 aug. 2024 · The formula for calculating is given below : Where, e = Super elevation. f =coefficient of friction. v = speed in kmph. R = Radius of the curve in metre. Putting all the values in the formula we get, ∴ e = 0.201 – 0.15 = 0.051 per meter of carriage way. ∴ Super elevation = 0.051 * 7 = 0.357 m or 35.7 cm above the inner edge of the road. Webdownward force on the outside rail of the curve that is greater than the downward force on the inside rail (Refer to Figure 1). The greater the velocity or the smaller the radius of the curve becomes (some railways have curve radius as low as 100m), the farther the resulting force Fr will move away from the centre line of track. is becoming a flight attendant hard
