We learn from Genesis 4:22 that Tubal Cain was an instructor of every artificer in brass (probably copper) and iron. We can trace back to this person the ancient craft of blacksmithing. Just how much he knew of expansion and contraction as applied to metals we do not know. But we do know how important the principle of expansion and contraction is in the engineering industry. Shrink fitting is one of its most common applications.
