A Da Vinci Bridge – 15th Century Engineering

Tuesday, 23 October 2018

Okay 1502 AD is technically the 16th Century, but the engineering was already in existence.

VERY cool – You can build it on the spot if there’s available timber, no connectors required, and you can knock it down and take it with you once your army has crossed the stream, arroyo, ravine or ditch. Here’s one in use (with planks installed):

This kid constructed one without notches or connectors, using friction and compression only.

“Don’t worry Ma’am, I’m from the Internet.”

It’s brilliant. I’m guessing it’s a methane collector connected to a burner to provide lift to the parachute. I’d name the single-user gas-fired flying machine “Jack The Ripper.”

Tension and Compression

Tension & Compression

A demonstration of the mathematical principles of the original Forth Bridge in Scotland performed at Imperial College in 1887. The central ‘weight’ is Kaichi Watanabe, one of the first Japanese engineers to study in the UK, while Sir John Fowler and Benjamin Baker provide the supports.

Long-span structural engineering illustrated. Note that weight is not the problem with this truss, but uplift is, hence the weights at the extreme ends of the truss. Tension is transferred from the exterior weights through the arms of the two men near the ends of the span, while compression struts keep this structure from collapsing under the dead weight of Mr. Watanabe.  Note also that without the weight provided by Mr. Watanabe, this structure collapses (unless Messrs. Fowler and Baker scooch over and hold hands).

Brute Force Cybernetics Turtle
Tinius the Cybernetic Turtle c1950 – An engineering student takes a robot through its paces, 1950.  [RH-2013- Although looking like a turtle (tortoise) which suggests being a Grey Walter-inspired machines, With it two “eyes” appearing as though it is fixed to the steering, suggests more that it is just phototropic i.e. it is attracted to and will follow a light source as per Norbert Wiener’s Moth.]

Nope. That’s not a charcoal study by MC Escher. That’s a photograph. Eyeball it for a bit – story and more photos below the break.
