Question

why do school bags have broad straps what is a problem A school child can face if the straps are narrow ​

Answer 1

Answer:

As, pressure is inversly proptional to area, which means less area will have more pressure than broader or larger one. School bags must have broader straps because it helps to reduce the pressure on the school child's shoulders. Narrow straps can cause pain in the student's shoulder because it apply more pressure on the shoulders and as pressure will incerease then the force acting on the shoulders will also increase because pressure is directly proportional to force. So we should always prefer bags with broader straps because it will cause less pressure and also reduces the force of bag acting upon shoulders.
