A steel 'stay' of effective length 5m is fitted in between the walls of a ships refrigerated compartment when the temperature is 18 degrees centigrade.
Assume zero stress in the stay on completion of fitting. when the temperature falls to -10 degrees centigrade, the gap between the walls is reduced by 0.5mm.
Determine the stress in the 'stay' at this temperature.

Coefficient of linear expansion = 11 x 10^-6 per degrees centigrade.

Modulus of Elasticity = 210 GN m^-2
