Question

Why porters place a round piece of cloth on their heads, when they have to carry heavy loads?​

Answer 1

Answer:

By placing the thick round piece of cloth on their head, the porter increases the area of contact of load with their head. Now the force of load falls on the larger area due to which the pressure on the head decreases and it becomes easier for a porter to carry the heavy load.

The round piece of cloth on their heads increases the area on which the force (weight of the load) will act. We know that, the pressure is inversely proportional to area. Therefore, increase in area reduces the pressure and this helps the porter to carry the heavy load easily.
