- The Steel Crane Rails Of Mrt Are Laid With Their Adjacent Ends 3 2mm Apart When The Temperature Is 15 C Then Length Of 1 (22.65 KiB) Viewed 63 times
The steel crane rails of MRT are laid with their adjacent ends 3.2mm apart when the temperature is 15°C. Then length of each rail is 18m. Coefficient of thermal expansion is 0.0000117/°C and E= 200 000MPa. Determine a. Temperature at e-which the rail will touch end to end. b. the gap between adjacent ends when the temperature drops to -10°C c. the compressive stress in the rails when the temperature reaches 45°C.
