Question

why does the pointed end of the nail gets into wooden planks easily

Answer 1

Answer:

Explanation:

This is because the pressure is inversely proportional to pressure.So when the surface area of point of the nail is less as it is pointed.It easily gets into the wooden plank.

More the surface area less will be the pressure.

Less the surface area more will be the pressure

Answer 2

Explanation:

A nail has a pointed tip so that when it is hammered, the force of the hammer is transferred to a very small area of the wood creating a large pressure that pushes the nail into the wood.

P=A/F​

P: Pressure

F: Applied force

A: Cross-section area

Here we can see pressure is inversely proportional to the area of the object's surface.
