A 10-m section of steel rail has a cross-sectional area of 7500 mm2. Both ends of the rail are tight against adjacent rails that can be assumed to be rigid. The rail is supported against lateral moment. For an increase in temperature of 50°C, determine a) The normal stress in the rail. b) The internal force on the cross section. (E = 200 Gpa and a = 11.9x10-6/°C).
