A brass rod length 50 cm and diamteer 3.0 mm is joined to a steel rod of the same length and diameter. What is the change in length of the combined rod at 250^(@)C if the original length are at 40^(@)C ? Coefficient of linear expansion of brass and steel are 2.10xx10^(-5) .^@C^(-1) and 1.2 xx 10^(-5) ^(@)C^(-1) respectively.

A brass rod of length 50 cm and diameter 3.0 mm is joined to a steel rod of the same length and diameter. What is the change in length of the combined rod at 250^(@)C , if the original lengths are at 40.0^(@)C ? The ends of the rod are free to expand (coefficient of linear expansion of brass =2.0 times 10^(-5)K^(-1) , steel =1.2 times 10^(-5)K^(-1) ).

A brass rod of length 50 cm and diameter 3.0 mm is joined to a steel rod of the same length and diameter. What is the change in length of the combined rod at 250^(@)C , if the original lengths are at 40.0^(@)C ? Is there a 'thermal stress' developed at the junction ? The ends of the rod are free to expand. Coefficient of linear expansion of brass = 2.0 xx 10^(-5).^(@)C^(-1) and that of steel =1.2 xx 10^(-5).^(@)C^(-1) .
