A horizontal steel railroad track has a length of 100 m when the temperature is 250 C. The track is constrained from expanding or bending. The stress on the track on a hot summer day, when the temperature is 400 C, is –
(Note: the linear coefficient of thermal expansion for steel is and the Young’s modulus of steel is )
