Why is it difficult to hold a school bag having a strap made of a thin and strong string?





please help me............​

Answer 1

Answer:

It is difficult to hold a school bag having a strap made of thin and strong string because the area under the strap is small. Hence large pressure is exerted by the strap on the fingers or shoulders. Due to the large pressure, the strap tends to cut the skin and hence pain is caused.

$\huge\sf{Answer:}$

Usually, bags made up of thin straps have made us very difficult to handle. But the bag with broad straps are very easy to handle.

$\tt\red{Let's \ know \ why \ such \ things \ happen.}$

IN CASE OF BAGS WITH THIN STRAPS:

The straps has a less contact area which falls in our body [especially shoulders]. This increases the pressure falling in our shoulders. As pressure increases, we feel pain in our shoulders and it is very difficult to handle.

IN CASE OF BAGS WITH BROAD STRAPS:

The broad straps usually have a broader contact area. This decreases the pressure falling in our shoulders and it is very easy to handle.

Now a days, industries make bags with broad straps as above the following scientific reason.
