Question

why tip of needle is sharp

Answer 1

Here is your answer......


The tip of a sewing needle is sharp so that due to its sharp tip, the needle may put the force on a very small area of the cloth, producing a large pressure sufficient enough to pierce the cloth being stitched.

Answer 2

The tip of the needle is very sharp, so that it has minimum amount of surface area and can exert the highest pressure on the surface to which it is applied for sewing. In the sewing needle tip, as we know, the surface area is less. Hence the pressure exerted will be more.
