A brass rod of length 50 cm and diameter...

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 (Co-efficient of linear expansion of brass =` 2.0 xx 10^-5K^-1` steel = `1.2 xx 10^-5 K^-1)`.
