A porter keeps a round piece of cloth on his head while carrying heavy load so that
the surface area increases causing the force applied to be spread over a larger area and reduces the pressure

Answer:
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.
