Explain why school bags are provided with wide straps to carry them - 102
ashwinthomas7em:
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.

As we know that pressure is inversely proportional to area, so an increase in area means decrease in pressure.
School bags are provided with broad straps to increase the surface area in contact with the shoulders and reduce pressure on the shoulders.
If thin straps would be used, then surface area in contact with the shoulders would decrease which will lead to increase in pressure on shoulders..
I hope useful answer for you
