What are the two most common bridges that are built today?

How are two identical steel columns utilized to support a level beam?
Two identical steel columns are used to support a level beam by being placed vertically on either side of the beam, providing equal and opposite forces to keep the beam in place.
What forces act upon arch bridges?
Tension and compression are the two forces that act upon a bridge.
What is the main difference between an arch bridge and a suspension bridge?
Arch bridges are in the shape of an upside down "U" with mainly steel beans, while supension bridges have one or two Major verticle beams with strong wire connecting to the bridge.
How are beam and suspension bridges alike?
A suspension bridge deck is suspended from above on a catenary cable between two fixed points. The Golden Gate Bridge is a suspension bridge. Using suspension techniques, great spans with minimum obstruction under can be created. A beam or truss (reinforced beam) bridge deck is supported from underneath on a construction of beams or arches (bent beams). longer, stronger spans favour the beam truss method of construction, especially where wind generated sway is an issue. The Sydney Harbour Bridge is a Beam/Truss bridge.
How does a beam bridgde work?
okay its a little complicated but if you read carefully you'll understand. get one beam and then get another beam, and then get another beam and put it on top of the other two beams you've already got and wala... u got urself a beam bridge. have a nice day and go skrew yourself =)
What kind of a bridge is the tower bridge?
No, it isn't. A beam bridge is a beam supported at each end. If you need to cross a ditch one way is to simply span it with a one inch board, then walk across. This is a simple beam bridge. Tower bridge is a bascule bridge. A beam bridge wouldn't do here because the bridge is located downstream of the Pool of London and London docks. Very large ships needed access to this dock area which meant good width and a high overhead clearance. Tower bridge has a tower at each end, with the towers connected to each other by a gantry close to their tops. The roadway, which is not very high above the river, is in two pieces. Each piece is hinged at the tower end, and can be raised to an almost vertical position. When a large ship needs to pass through the bridge, the two bascules are raised, then lowered again as soon as the ship is through. The name Tower bridge has nothing to do with the towers at either end. The bridge is located very close to the Tower of London, a fortress that was put there about 700 years previously.
What are two examples of thermal expansion in solid?
Two examples of thermal expansion in solids are the expansion of a metal rod when heated, causing it to increase in length, and the expansion of a bridge beam on a hot day, resulting in the beam bending slightly due to the increase in temperature.
What is the longest bridge in New Zealand?
The longest bridge in New Zealand is the State Highway 1 bridge over the Rakaia River, around 50km (30mi) south-west of Christchurch. The bridge is a two-laned beam bridge, and from end to end measures 1757 metres (5765 ft).
What shape has best section modulus?
The answer depends of the forces applied to the beam: - for a single-directional force, the answer is a hollow rectangular shape (with the force applied on the narrow face); an I-beam is the second best. - For forces applied in two perpendicular directions, the answer is a hollow square section. - For forces applied from any direction, the answer is a hollow circular bar - a pipe.
