Question

Why do school bags have broad straps? What problem can a school child face if the straps are narrow?​

Answer 1

School bags have broad straps because in broad straps area is more so the pressure will less and due to which child can hold a bag with less load

On contrary if the straps are narrow then area will be less and pressure will be more and by holding the bag child will get more load

♤Pressure is directly proportional to area
