Answer 2

It is difficult to insert a blunt nail in a wood block because -

• We know that ,

A sharp nail's tip area < A blunt nail's tip area.

• Now, suppose we generate a force of X by one hammering strike.

According,to the equal distribution of force policy,the applied for will be equally distributed in the tip's area.

• Now,greater the tip's area means less the force in a point of the tip which will strike the wood because the initial applied force is constant.

• So,in the sharp nail,all the force is concentrated into the small tip which makes it easier to insert in a wooden block.

And,the complete opposite thing happens for a blunt nail.
