Answer:
Pressure=Force/Area
Explanation:
We can take example of a nail. For hanging frames on a wall, we put the pointed side of a nail towards the wall and hit the broader part with hammer, due to which the nail enters the wall. So, when area is less, then pressure is more.
Similarly, bag straps have larger area so that pressure is less.
