Q59 of 100 Page 209

Explain why, porters place a thick, round piece of cloth on their heads when they have to carry heavy loads.

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.
