Question

explain why porters place a round piece of cloth on their head when they carry heavy lods.

Answer 1

porters place a round piece of cloth on their head when they carry heavy lods as the round piece of cloth increases the area on which the load is placed. We know that when surface is more than pressure is less. As a result, the pressure on their heads get reduced.

hope this will help

Answer 2

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 thepressure and this helps the porter tocarry the heavy load easily
