Example 2.36. A railway is laid so that there is no stress in the rails at 8°C. Calculate (a) the stress on the rails at 50°C if there is no allowance for expansion, (b) the stress in the rails at 50°C if there is an expansion allowance of 8 mm per rail. (c) the expansion allowance if the stress in the rail is to be zero when the temperature is 50° C (d) the maximum temperature to have no stress in the rails if the expansion allowance is 12 mm per rail. The rails are 30 m long. Take a = 12 x 10-6 per °C and E= 2 x 10³ N/mm².
