Noted that the equation of pressure is Force/Surface Area. Therefore the wider the straps the lesser the pressure. ... School bags usually have broad straps so that the weight of the bag may fall over a large area on the shoulder producing less pressure and less pressure, it is comfortable to carry heavy bag.

Answer:
They usually have broad straps because by this the pressure will decrease and it will be easier to hang it up.
Explanation:
Suppose if we hang any bag with thin straps than the pressure will increase and will become hard to carry it.
Why this is so?
it is comfortable to carry a broad strapped bag than a thinner one because area of contact increase on straps and the pressure on shoulders become less.
As we know that pressure = force/area.
the pressure increase in thin strapped bags.
