this is a great demonstration. what I like is that you can fairly intuitively understand that these different mechanisms were invented to solve specific problems that the others don't address.

[@SofosProject]

I can tell as much, but not specifically what. I was mostly thinking about what the most energy efficient method was. The tilt, table, and vert-lift seem to be at a disadvantage by how high they can be raised. All the others will permit ships of arbitrarily large height. Perhaps those are easier to use, because you're not putting the fulcrum at the end of the bridge, but rather along the wide edge or all corners at once (to spread the energy evenly).

The Eiffel tower of bridges (seriously, Alberto Palacio, the engineer, was a student on Eiffel studio).

We have one in France, at Rochefort, near La Rochelle (Charente Maritime region). It's almost never used and it's more like a remnant of a distant past. Its mechanism is told to be a real pain in the a$$ to maintain. I guess those bridges are used only for places where you don't often have to transport something from one side of the river to the other...

[@Tolono]

If there's ever a part 2, consider including the "Strauss Bascule." The most common design uses a parallelogram linkage and they are found all over Chicagoland (mostly for railroads), as well as lift bridges (7:15), Scherzers (1:21), and some old designs that are now locked in place including a Rall bridge, Page bridge, and bobtail swing bridges. There's a PDF called "Historic Chicago Railroad Bridges" that explains more about them.

[@danielscheeler5559]

The folding bridge looks the most unstable. I hope in real life, reinforcements are added so that it doesn't bend as much as this one did. Well done on this!

yes. u have multiple pauses and beams supporting each stage of the bridge and all ur doing is making the person in the car stop and go every 2 seconds because they re waiting for every bridge to go up and down. even then its very likely u could combine 2 bridges into 1 and it still work rather well.

I can't help but wonder, why would you pick one bridge over another? Where's the shots of something going wrong and a new bridge coming in that addresses that problem? I like seeing iterative design in action- or at least some pros and cons.

[@hothi92]

It's usually due to specific use cases. Some places don't have the space for the bridge section to lift in a specific direction. Or the bridge can't support the weight or something over a section lifted or turned or what have you. Sometimes it's because they can and it looks cool

[@airplanes_aren.t_real]

​@@hothi92 also they need to take into account what the bridge will be used for

[@mdccxxvii]

The size of the boats that will be passing through is also a major consideration.

[@davidaugustofc2574]

Money, Available Materials and Long Time Maintenance are also major considerations

[@daanwilmer]

It's not so much things going wrong where another bridge is needed, it's more a matter of available space, money, and materials, and requirements in terms of traffic
