BCP 201 GD: Bones 5 E-H (First Timers)

The head of a bird bone (the top of it) may have dense spongy bone in it.

The woodpecker has dense, strong trabeculae in its skull like a hawk has in its wings. But the woodpecker’s are even stronger. These help the bird survive its 1200 head-slams a day.

The picture below is a good example of “trabs in trabs” (trabecular-type bracing in trabecular-type bracing).

Cross members in bridges, cranes, gates, roofs of buildings and toilet plungers often have “trabecular design”.

Built in 1889 for the World’s Fair in Paris, the 1063-foot Eiffel tower is a stunning example of using crossmembers and bracing of all kinds to keep a structure standing.

There are pictures in this article of bracing in buildings in Taiwan that combine arches and bracing.

Some Roman aqueducts were built with no mortar at all yet are still standing today after 1000 years!

Taiwan, Japan, and the Philippines are all islands more than 1000 miles off the coast of Hawaii.
