Question

We use towels to reduce pain on hand while carrying a bag with a handle made of thread. Give reason
Anyone please help me solve this​

Answer 1

Answer:

The simple reason is behind surface area

Explanation:

We use towel to reduce pain on hand as towel has a large surface area, It won't pains but when it comes to a handle of bag, It surface area is small which leads to put more stress in our hand

Mathematically

Stress = Force / Area

when Area increases stress decreases and when Area decreases stress increases

and when stress increases it pains.
