Question

why are board pins made sharp?​

Answer 1

Answer:

Board pins are made sharp as they can easily penetrate the surface of the soft board .

Answer 2

Answer:

So, that pressure is maximum.

Explanation:

Pressure is defined as thrust per unit area. So, pressure is directly proportional to thrust, or the force acting vertically downwards, and inversely proportional to area. So, when board pins are made sharp, the area is less, and so, the pressure exerted is more.
