A steel crane rail tracks laid with their adjacent ends 5mm apart. In the spring when the temperature is 20 Degrees Celcius, the length of each rail is 20. The coefficient of thermal expansion is 1.20E-5/Degress Celcius and the Young's Modulus is 201590MPa. a) Determine the temperature in celcius at which the rails will touch end to end b)Determine the gap between the adjacent ends during winter when the temperture is at 5 Celcius c) Determine the compressive stress in the rails when the temperature is at 40 Celcius
