Question

explain why railway tracks are laid on large sized concrete sleepers

Answer 1

hi friend
here is your answer

-----------------------------------------------------------------------------------------------------------------
we have seen that the railway tracks are laid down on the large sized concrete sleepers because as the concrete sleeper has very large size and that large size helps to reduce the pressure on the ground.
As large surface area reduce the pressure and the small surface area increase the pressure.
as the pressure is inversely proportional to the area if we increase the surface area then we get reduced pressure.
so in order to reduce pressure the concrete sleeper are very large sized that are laid down on railway tracks.
so this large size concrete sleeper are nothing but reduce the pressure on the ground.

hope this is helpful to you so please mark it as brainliest

Answer 2

coz if they r directly put on earth they will sink down due to extreme pressure it would exert on earth cen run over by a train
