Question

If you are unable to pierce a thick sheet of paper what conclusion will you draw?
a) pins cannot pierce the thick sheet of paper.
b) the weight of the pin has to be more to pierce it.
c) the area of the pointed end is too large, so the force exerted cannot produce enough pressure to pierce it.
d) only some pins can pierce it.

Answer 1

I would say option d

only some pins can pierce it.

Answer 2

Answer:

Option C= The area of the pointed end is too large, so the force exerted cannot produce enough pressure to pierce it.

Explanation:

If the end of the pin is blunt, then there will be less pressure exerted because Pascal=1/Area.

So the end should be sharp enough to exert more pressure and pierce the thick sheet.

Pressure=Thrust/Area
