Gaps are left in between railway tracks. Give Reasons.
Answers
Answer:
The gap is left between the rails to provide a space for the iron metal to expand and contract during the summer and winter season due to the change in the temperatures. If the gap is not left in between then the rails will bend more and cause derailing of the trains.
Hope it helps.
Answer:
These gaps which are of the order of a few millimeters, are provided to allow room for the rails to expand the rise in temperature due to the atmospheric temperature as well as the friction caused by running of train. All materials expand when heated and contract when cooled.If that gap is not left then the tracks might have enormous stress in them while expanding due to heat. Thermal expansion of long continuous sections of rail tracks is the driving force for rail buckling.
