“Before we look at this bridge, where was DaVinci on race?”

************************************************************

Pssshaw...the idiot likely thought all lives matter, or some such foolishness. These geniuses of today could task themselves to hunt down all statutes so he can be cancelled, and proclaim the world would be a better place if there were never any da Vincis. /s

And next month Popular Mechanics will post an article on how to use science to tear down this bridge designed by a white guy.

That would have been “a new wonder” of the world. It would have been huge.

.

Proving a design ‘works’ is one thing (ignoring that its also ‘proved’ on paper) .

Having a way to actually build it to have that DESIGN is a whole nuther thing.

What you do is, you dry up the river by diverting it....

In this instance it's not a river.

It's an estuary or strait that joins the Black Sea with the Sea of Marmara.

Aside from the very strong and rapid currents, the depths, 120 ft min to more than 400 feet make it extremely difficult if not impossible to divert the marine passage.

The use of caissons such as pioneered in the building of the Brooklyn across the East River of NYC would not have worked as compression sickness occurred working at depths less than 80 feet.

Those conditions, likely unknown to Da Vinci, also make the use of stone construction supporting scaffolding hugely problematic. While at various times chains were used across the strait to block naval intrusions I doubt the powerful currents and tide would allow for anchored barges to support construction scaffolding, not to mention the difficulties of transporting and lifting the stones, but with Da Vinci who knows.

Just as with construction of the first cathedrals there would have been many failures and deaths along the way.

Check the current bridges...long span suspension bridges, and one of which IIRC is a swing bridge.

Edison was not an inventor. He was a business man and an innovator, who’s company improved upon other people’s designs.

No discussion about compression and limits of the stone?

Lower arch = bigger numbers.

why the da Vinci used a ‘pair of pants’ design

Guessing ... as the vertical load is transferred to horizontal thrust that must be contained.
A wide foundation would help.

If the thrust blocks move, get ready to swim.

Yeah... those are kind of key aren’t they? Da Vinici’s notebooks were full of harebrained ideas for which he lacked true scientific background to develop. He kind of intuited a lot of stuff.

Agreed... but the amount of thrust doesn’t change much regardless of whether it’s a ‘pair of pants’ design or a full width design. In fact, the pair of pants has a higher load concentration since the thrust is taken up by a smaller area.

Stay with the mental images, there may yet be more undiscovered Da Vinci noyebooks, drawings, evidence of symposia he attended with space aliens.

In any case Da Vinci's design was brilliant for its day....just highly unlikely it could have been built there at that time....like much of his ideas.

Well thank you! Very informative.

Most of all, thank you for NOT being a douchebag in your response. Way too much of that going on these days.

I drove under that bridge while on vacation a few years back.

Just sitting around on the porch on a friday night jawin’ with the fellows when something really interesting and odd comes up, and first guy says, “what if..” and the next one says, “hmm, lemme get some maps..”

And yeah...been a lot of uncivil posting in tongues lately....
