Question

Why is it easier to hammer a sharp nail respective to a blunt nail?

Answer 1

1. It is easier to hammer a sharp nail respective to a blunt nail.
2. This is because when force is applied to the head of the nails, the pressure exerted on tip of the sharp nail is more due to the small area than the blunt one.
3. As we know from pressure expression, $Pressure=\frac{Force}{Area}$, pressure is inversely proportional to the area.
4. Which enables the sharp nail to pierce a surface easily.
