Question

Railway tracks are laid on wooden or cemented sleepers. This is because they

• A. Increase the pressure of the train
• B. Increase the speed of the train
• C. Increase the area so as to reduce pressure
• D. Decrease the area in order to increase pressure

Answer 1

The correct option is C Increase the area so as to reduce pressure

We have seen that the railway tracks are laid down on large-sized concrete sleepers because the concrete sleeper has a very large size and that large size helps to reduce the pressure on the ground. As the pressure is inversely proportional to the area if we increase the surface area then we get reduced pressure.So this large size concrete sleeper is used to reduce the pressure on the ground.
