Given:

A blacksmith hammers a hot piece of iron while making a tool.

To do:

We have to explain how the force due to hammering affects the piece of iron.

Solution:

When a hot piece of iron is beaten with a hammer then, a force is applied to the iron piece. Let us discuss the effect of force due to hammering on the hot iron piece:

Forces are of two types-

1. Balanced force:

A balanced force can change the shape and size of an object but can not bring it into motion from the rest or vice-versa.

2. Unbalanced force:

An unbalanced force can bring an object into motion from the rest and vice versa but can not change the shape and size of the object.

Effect of hammering on a hot piece of iron:

When a hot piece of iron is hammered by a blacksmith, a balanced force acts upon the hot piece of iron due to hammering that changes the shape of the hot iron piece into a desired shape to make various items such as nails, screws, knives, iron gates, etc.
