Q.6 A blacksmith hammers a hot piece of iron while making a tool. How does the force due to hammering affect the piece of iron?

A blacksmith hammers a hot piece of iron while making a tool, because iron is a metal and has the property of malleability and ductility due to which it can be beaten while heating to get the required shape.

The force due to hammering causes the change in the shape of the iron and thus iron can be moulded in the shape of the required tool.
