Stress in Rail Head Solution

STEP 0: Pre-Calculation Summary

Formula Used

Bending Stress = Bending Moment/Section Modulus in Compression
S_h = M/Z_c
This formula uses 3 Variables

Variables Used

Bending Stress - (Measured in Kilopascal) - Bending stress represents the stress due to the bending moment caused by the vertical loads.
Bending Moment - (Measured in Newton Meter) - The Bending Moment is the reaction induced in a structural element when an external force or moment is applied to the element, causing the element to bend.
Section Modulus in Compression - (Measured in Cubic Meter) - Section Modulus in Compression is the geometric property of structure to find the strength.

STEP 1: Convert Input(s) to Base Unit

Bending Moment: 1.38 Newton Meter --> 1.38 Newton Meter No Conversion Required
Section Modulus in Compression: 52 Cubic Meter --> 52 Cubic Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

S_h = M/Z_c --> 1.38/52

Evaluating ... ...

S_h = 0.0265384615384615

STEP 3: Convert Result to Output's Unit

26.5384615384615 Pascal --> No Conversion Required

FINAL ANSWER

26.5384615384615 ≈ 26.53846 Pascal <-- Bending Stress

What is effect of Leading wheel?

When a load is applied on a rail, it causes certain deflection and a wave-like effect is created in the rail with the passage of the train. The portion of the rail immediately under the wheel gets depressed due to wheel load and the portion ahead of the wheel gets lifted creating a wavy formation. The effect of the lift in the rail on bending stress is considered only when the lead axle is at a distance greater than six times the distance of the point of contra flexure from the load.

How to Calculate Stress in Rail Head?
