applications based on the concept of pressure:
(i) As we know, the area of a sharp edge is much less than that of a

area, i.e., the pressure is more for the sharp edge than the blunt edge.
(ii) Railway tracks are laid on large sized wooden
sleepers, which spread the force due to the weight of the train on a larger
area, thus reading the pressure considerably.
