Give two practical daily life applications that make use of the concept of pressure.

**Answer:**

Practical applications based on the concept of pressure:

- As we know, the area of a sharp edge is much less than that of a blunt edge. Thus, for the same force, the effective force per unit area, i.e., the pressure is more for the sharp edge than the blunt edge.
- 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 reducing the pressure considerably.
