Answer 1

Hello,

Bcoz it is easy to carry.. The force is distributed over a large area


Don't know about that.. Thnx

Answer 2

As we know that if surface area is smaller...the pressure is larger.
So the edges of a knife is sharp so that it can be easy to cut something.

☆If surface area is larger, the pressure is less..So in order to reduce pressure on shoulders,, the straps of the bag are made wide.
