Thermal expansion gives temperature stresses that are resisted by the weight of the rails. If the resistance provided per km of rail length is 700 kg, then find the maximum length of the continuous welded track that can be provided, neglecting all other factors.
Given for the rail:
Area of cross-section = 50 cm2.
Modulus of elasticity = 2 × 106 kg/cm2.
Coefficient of thermal expansion = 1.2 × 10-5/°C
Rise in temperature = 35°C
