Question

It is difficult to cut cloth with blunt blades.Explain

Answer 1

pressure is inversely proportional to area therefore less the area more is the pressure and more the area less is the pressure therefore it is hard to cut a cloth with blunt knife

Answer 2

Hey there!

The area is larger of blunt blades to comparison to sharp edges blades.

We know,

$\boxed{\text{Large Area }\to \text{Less Pressure}}$

So, due to large area, blunt blades have low pressure. 

Hence, it is difficult to cut the cloth using a scissor with blunt edges.
