Did You Know?
By weight, human bones are stronger than steel.
Human bone is indeed stronger than steel but only if the two are compared in terms of weight. This is an important distinction because steel by nature is a denser material than bone. The human bone is not as dense as steel because of its need to be light.
The human skeletal system, in fact, accounts for only about one-sixth of your weight. If human bones were as dense as steel, they would be much stronger than they are now but also make it very difficult for humans to move.
So, the big question is, how much stronger is human bone than steel? Roughly speaking, human bone is about five times stronger than steel if both of them have the same weight.
If you take a bar of steel of the same size as a piece of bone then you’ll see that the bar of steel is about three to five times heavier than the bone. This is because the bar of steel is denser than the piece of bone.
