Answer 1

Answer:

The same force acting on a smaller area exerts a larger pressure, and a smaller pressure on a larger area. This is the reason why a nail has a pointed tip, knives have sharp edges and buildings have wide foundations.

For example, When standing, a person will sink more into sand than when he lies flat stretched on sand. The body weight acts on a smaller area, in standing position, than when the person lies stretched over a larger area.
