Question

Why are iron rails of railway tracks fixed over wide wooden or concrete sleepers

Answer 1

The sleepers have two main functions:
i) They serve the purpose of fixing the rails together to prevent derailing. The sleepers are fixed perpendicularly and hold the rails uniformly along the trail.
ii)The second reason has to do with pressure, and this is why the wooden or concrete sleepers are fixed over a wide region to spread out the load due to the moving train-the wider the area, the less the pressure exerted. With the absence of the sleepers, the rails would sink into the ground due to the heavy load.

Answer 2

Answer:

Wider the area, lesser the pressure exerted.

Explanation:

Wooden or concrete sleepers are fixed over a wide region to spread out the load due to the moving train. The wider the area, the less the pressure exerted. In the absence of the sleepers, the rails would sink into the ground due to the heavy load of the moving train.
