Question

What modifications can be made in the school bags to reduce the effects of heavy loads

Answer 1

the broader stripe should be used in bags to decrease the pressure.

Answer 2

You know that when area is increse then pressure will decrease.example ,we can chop vegetables easily with a sharp knife but with a blunt knife we cannot chop vegetables easily.

Same thing with our bags, the broader stripes is given means area increase so pressure will decrease
This is the criteria with our bags.This helps us to carry heavy loads.
