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

Answer:
Practical applications based on the concept of pressure:

  1. 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.
  2. 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.
