@Jack_Callcott_AU, A catenary shaped hanging chain is just a real world illustration for principles that are still applicable to an arched bridge with a parabolic shape. And since the shapes are slightly different, so will the mathematical functions that model them.

1:48. Pretty sure that the triangle (A-frame) is stronger if(!) the load is only applied in the middle as in your example. Scissor lifts are a good example where such a design is used. Of course that is not practical for a bridge where the load needs to be distributed across the whole length.

It would have been further East of Panama and would have included Present day Colombian territory. The 2 reasons as to why they did not make it so was not because of Colombia but they saw no Money and Power/Control by making it a Sea Level Canal so they went with the Locks instead.

When you do a video on tie-arch bridge, take a look at Lupu tie-arch bridge on Huangpo river in China. I think this bridge has a flaw design. It is still standing, but they had to add more steel cables to hold the arch from collapsing. I don't expect this Lupu bridge to last long. The Sydney harbour bridge is the true engineering marvel. The best bridge design and built of all times. Suspension bridges are very costly to do maintenance. Turkey just had the longest Suspension bridge in the world. Its support tower look a bit skinny. How long will it last?
