Question

why is the design of the strap an important point for bag selection? I justify your answer. ​

Answer 1

$\huge\fcolorbox{black}{lime}{AnsweR:}$

Broad shoulder straps provide larger surface area. So, the pressure exerted by the bag on the shoulder is less and carrying the bad is easier.

Because the surface area increases and so as we know that area is inversely proportional to the pressure so the pressure decreases and we find it easy to carry our school bag.

Or

Larger the area smaller the pressure. School bags usually have broad straps so that the weight of the bag may fall over a large area on the shoulder producing less pressure and less pressure, it is comfortable to carry heavy bag.
