A steel Railway track in kaduna has a length of 27 metres when temperature is 35° Celsius a. what is the length on the Third Day when the temperature is 44 degree celsius
B. suppose the track is held firmly to the ground so that it cant expand 10 as stress result in the track due to the temperature change take young modulus of Steel as 2.0 x 10 1m square and coefficient of linear expansion of Steel as 1.1×10-³⁰c
