Question No. 10.10- A brass rod of length 50cm 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 ^o C, if the original lengths are at 40 ^o C ? Is there a thermal stress developed at the junction? The end of the rod are free to expend (Coefficient of linear expansion of brass 2.0 x 10^-5 , steel =1.2 x 10-5 K^-1 )| ncert class 11 NCERT questions physics chapter- Thermal Properties of Matter solution by ujwal Kumar physics master | Best Platform for all physics students.
