Ok, here's the explaination--
We know that Pressure = Force/Area
i.e P=F/A
Which, clealy shows that pressure is inversly proportional to area, that is if area increases, pressure decreases. So, that is why if we keep the end side of the nail which has very small area ,in contact with the wood then get to apply less pressure on the broader side of the nail which make it easier for us to fix it into the wood.
ok if you keep the broader side of the nail in contact with the wood and hammer the other side, due the the larger area of the nail you have to apply A-LOT of pressure compaired to the previous case.
I hope that helps!

Answer:
We hammer the broader side of nail and not its sharp end to put it in wood. ... With the force being the same and area being less, the pressure acting on the wood will be the maximum(pressure=force/area) The more the pressure, more is the extent to which the nail enters the wood.
