“A key design feature shared by many 100-year-old barns and some modern skyscrapers is that the external shell carries the building’s load with a minimal use of internal columns for support. Internal floors and walls, if any, function in a structural way to stiffen the building. This resourceful design allows for a very strong structure with a maximum of interior space available for other purposes.
The bones in the human body capitalized on this design feature long before farmers and architects did. In fact, studying bone construction and function provides a mini-course illustrating important engineering principles.
Sophisticated Engineering Properties
A quality product begins with materials that have superior engineering properties. Bone is constructed much like reinforced concrete, in which a cage of steel reinforcing bars (“rebar”) is embedded. The reinforcing “rods” in bone are made from minute strands of collagen fibers, 360 of which could be put end-to-end in the width of a human hair.
Each fiber is composed of three substrands wound in rope-like fashion around each other so tightly that along the area of contact only the smallest amino acid would fit in the space between the strands. In order to work, this particular amino acid would need to be designated for every third position in each strand–which is exactly what is specified in the DNA code. Collagen fibers are linked so strongly that their resistance to being pulled apart in tension is actually greater than the resistance present in an equal amount of steel rebar…
