Why it is comfortable to lift a school bag with broad straps than thin scraps?

Answer 1

hi frnd!!##@@____________________________
______________________________-----------------
it is comfortable to lift a school bag with broad straps than thin scraps so that the area of contact increases and thus the pressure on the shoulder is reduced.
HOPE THIS HELPS!!;-))

Answer 2

it is because in thin strips the pressure increases as pressure =force/area.
but in case of broad strips pressure decreases as area increases.but force will remain the same in both cases.
hope it helps......
