For a more comfortable train ride, the continuous welded rail technology, which consists of welding the rails and creating a uniform surface for the train to pass, is used. However, such a track must withstand thermal expansion in summer and winter. What temperature difference can a steel rail withstand if its linear thermal expansion coefficient is 1.63⋅10−5K−1 and the permitted stress of the rail is 600MPa? Assume that the tensile Young's modulus for steel is 195GPa.
