Question

explain why porter's place a round piece of cloth on their heads when they carry heavy loads .

Answer 1

Dear user,
As we all know that if we increase the surface area of an object,the less pressure will act upon us. Porter used a round to increase the surface area of their head,by this less pressure would act on his head.
Thank you.

Answer 2

Whe know that when the area of an object is larger the pressure is able to distribute more widely over the surface

Thus, when the porter ties a round cloth over his head the pressure is distributed over the cloth thereby reducing the weight on his head.

This makes the task easier
