why do school bags have broad straps?

We know that

pressure = force/area

so, if the area is more pressure exerted will be less and vice versa. This is the reason why shoulder strap in school bags are broad. This helps in reducing the pressure exerted on the shoulders of the person and thus makes it more comfortable to carry around.

hope this helps!!

If the area is more then the pressure will be more. If the area is less the pressure will be more. School bags have broader straps so that the pressure exerted on our shouldr will be less.

pressure =force /area

The pressure exerted by the straps on our shoulders will be divided on the surface of the straps. So when the straps are broader, the pressure is divided more, hence the pressure on our shoulders decreases.

it belong to thrust and pressure

A school is

because pressure=force/area

school bags have board straps because it increases the surface area and we able to carry them on our shoulders it makes it light weight also to carry them

Because pressure - force/area

Strips of bags are made broad to reduce pressure because as we know that pressure is inversly proportional to area. So, as the area increases the pressure decreases.

A school bag has wide straps made of thick cloth (canvas).so that the weight of bag may fall over a large area of the shoulders of the child producing less pressure on the shoulders making it comfortableto carry heavy bag

To decrease the pressure as the area is more pressure will be more and the area is less than the pressure will be more

To increase the surface area and decrease the pressure

Because it is easy to carry. A wider strap distributes the force throughout a greater surface area. You can do a comparison using a simple physics equation. So take two different straps and measure the area of them.

thrust =force exerted /area 
so ,this is why  school bags have larger surface area.As the area of the strap is more hence the pressure exerted by it on our shoulders will be less,by which our school bags weight will not be on us and we will be able to carry it easily without any shoulder pain.

Dear Student,
School bags have broader straps so that the pressure exerted on our should will be less. The pressure exerted by the straps on our shoulders will be divided on the surface of the straps. So when the straps are broader, the pressure is divided more, hence the pressure on our shoulders decreases.
