Question

Why are nails made very thin at one end and somewhat thick at the other end ?

Answer 1

Solution - Nails are made very thin at one end and somewhat thick at the other end because, They're thin on one end so that they are hammered in more easily, because when you apply force to an object and the object has a small surface area (such as the end of a nail) that force is exerted on a tiny area, thus goes in more than if you applied the same pressure on a larger surface area, for the force would just 'spread out' equally. And further it's thicker because then there's more grip, it's stronger etc.
