Question

give reason why is the strap of your school bag broad.

Answer 1

Because as AREA is increased, this results in less pressure on shoulders

⇒P∞1/A

Answer 2

The strap of your school bag is broad because pressure is inversely proportional to area so, if area is increased then pressure is decreased and if area is decreased then pressure is increased. So, the strap of bags are broad due to which it becomes less pressure on our soldiers and we feel comfortable and if the strap is not abroad then pressure on our soldier is more and irritate us that is why the straps of bags are abroad.
