Why are expansion gaps left between the rails of a railway track?

The gaps you are referring to the small gaps that are left between section of the rail that form each side of the parallel railways for over which railway engines, coaches, trains and trams run. 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. the extent of expansion and contraction is quite low to be noticed by people or make much difference in most situations. However, since each section of the rail is very long, the expansion due to heating is significant, and unless space is provided for expansion of rails, the rails will bend to accommodate the increased length. This will make the railway unfit for running of trains.


What is the space between the right and left lung?

The mediastinum


What would happen If gap is not left between railroads?

if gap is not left between railroads, it will expand in summer and will bend if no space is left


Why small gaps are left between successive rails in railway lines?

In the heat (of summer) the rails undergo thermal expansion. The amount of expansion is proportional to the normal length and, because rails are long lengths of metal, the expansion is sizeable. If there were no gaps then the expanding rails would push against one another until they buckled.


What does a ladder diagram for a flashlight look like?

In North America the diagram will have a left and right supply rail. The rungs are between these rails in a horizontal position. Usually the voltage supply is on the left and return to source is on the right. The rung will consist of a switch in series with a lamp drawn from the left rail to the right rail. That's it. In European countries the rails are top to bottom. The rungs are between these rails in a vertical position. Usually the voltage supply is on the top rail and the return to source is on the bottom rail. The rung will consist of a switch in series with a lamp drawn from the top rail to the bottom rail.

How do expansion and contraction work on the train line?

while the solar rays fall on the rails it gets heated and gets expanded,as every one knows metal expandas on heating....so the gap is left between the rail to rail...while it gets heated the gap covers without breaking of rails .


How is storage divided among multiple users of Linux?

Storage can be divided in any number of ways. If you use quotas, you can assign each user a specific amount of space. If you do not use quotas, each user can use as much space as they can, until there is no free space left.

What is in pulmonary cavity?

The pulmonary cavity is the space lined by parietal pleura that each lung occupies. The right and left pulmonary cavities are separated by the mediastinum. It is important to not confuse the pleural cavity with the pulmonary cavity. The pleural cavity is the potential space between the parietal and visceral pleura containing a small amount of serous fluid that surrounds each lung.
