3. Have you ever seen a blacksmith beating an iron piece? Do you find a change in the shape of these pieces on beating? Would you expect a similar change in wood log on beating?

Yes, I am aware that blacksmiths often work with iron or steel pieces by heating them in a forge and then shaping them using various tools, including hammers and anvils. This process is known as forging. When a blacksmith beats an iron piece, it undergoes significant changes in shape due to the plastic deformation of the metal. The intense force applied by the hammer reshapes the metal, allowing the blacksmith to create various forms such as bars, blades, tools, or decorative objects.

The change in shape occurs because metals, like iron and steel, have a property known as malleability, which allows them to be hammered or rolled into thin sheets without breaking. When subjected to force, the metal atoms can slide past each other, resulting in the deformation of the material while maintaining its integrity.

On the other hand, wood is a different material with its own set of properties. While wood can be shaped using tools like chisels, saws, and planes, the process is quite different from forging metal. Wood is a fibrous material composed of cellulose fibers held together by lignin, and it does not exhibit the same malleability as metals. While wood can be carved, cut, or shaped through cutting and removal of material, it does not undergo plastic deformation like metal when subjected to hammering. Instead, excessive force on a wooden log would likely result in splintering or fracturing rather than deformation.

In summary, while beating iron or steel pieces can lead to significant changes in shape due to plastic deformation, a similar change would not be expected in a wood log upon beating. Instead, wood is shaped through cutting and removal of material, rather than plastic deformation.
