A steel rod of length `0.5km` is used in the construction of a bridge. It has to withstand a temperature change of `40^(0)C`. The gap that is allowed for its expansion is `[alpha = 10^(-6//@)C]`

The length of the steel structure of a bridge is 0.5 km and it has to withstand temperature change from 44^(@)F to 116^(@)F . What allowance should be kept for its expansion if the coefficient of linear expansion of steel is 1 times 10^(-5@)C^(-1) ?

Two rods of equal cross sections, one of copper and the other of steel, are joined to form a composite rod of length 2.0 m at 20^@C , the length of the copper rod is 0.5 m. When the temperature is raised to 120^@C , the length of composite rod increases to 2.002m. If the composite rod is fixed between two rigid walls and thus not allowed to expand, it is found that the lengths of the component rods also do not change with increase in temperature. Calculate Young's moulus of steel. (The coefficient of linear expansion of copper, alpha_c=1.6xx10^(-5@)C and Young's modulus of copper is 1.3xx10^(13)N//m^(2) ).
