Question

The Truss Bridge

You already know about three types of bridges beam bridges, arch bridges, and suspension bridges. There are several other types of bridges including trus, cantilever, and cable-stayed sign. The fint of these bridges is much like the beam bridge, except it has additional braces. The members are allel tunes. This bridges are much more ngid than beam hedges in dition, the triangular structure of the trum helps to distribute the ridge's load ever a larger area. Due to this dotribution of forces bus bridges can be much langs than beam bridges

While bear badges are the allot type of bridge, trumm fridges are the earliest form of "mode" siges The first tus bridges were made of woot Wood worked well mitrally, but due to weather, the wood would become weak from rot. Some bridge builders attempted to solve this problem by putting for cover on the bije Thest covered edges can still be seen today. Another problem with wood bridges was the load the wood could support. The fint voniom of the locomotive were very small and not very heavy As locomotives improved, they became gnificantly fader and heavier Many wooden bum bridges neelod enforcement with on or sted. Some were tom down and replaced with newer venions of the trum bridge

Thus bridges were atayorized by the location of thar bruses. The three categories are a through trum, deck trum, or pony/hal-though trum. Truses and positioned higher than the deck of the bridge in a through trum bridge if the trames are lower than the deck, then the bridge a a deck br When the frames extend both under and above the roadway, it is called a half-through or pony trus

Can you tell to which category that bulges belang (Hint: Where is the deck or rosway?)

Atoms and Mages,Pula Skyway

Answer 1

Ответ:

Based on the information provided, we cannot determine to which category the Astoria Megler Bridge and the Atoms and Mages, Pula Skyway bridges belong. The text does not provide clear information about the design of these two specific bridges.
