Question

While carrying loads, the porter wears a turban on his head.

Answer 1

1. Pressure is defined as force per unit area, i.e., $Pressure=\frac{Force}{Area}$.
2. Pressure is inversely proportional to the area on which it acts, $P\alpha \frac{1}{A}$.
3. Porters use round pieces of clothes on their heads while carrying loads to increase the area of contact.
4. This would further reduce the pressure of the load on their heads.

Hence, while carrying loads, the porter wears a turban on his head.
