A suspension bridge is a type of bridge in which the deck is hung below suspension cables on vertical suspenders. The first modern examples of this type of bridge were built in the early 1800s. [5] [6] Simple suspension bridges, which lack vertical suspenders, have a long history in many mountainous parts of the world.
A simple suspension bridge (also rope bridge, swing bridge (in New Zealand), suspended bridge, hanging bridge and catenary bridge) is a primitive type of bridge in which the deck of the bridge lies on two parallel load-bearing cables that are anchored at either end. They have no towers or piers.
Suspension bridge (more precisely, suspended-deck suspension bridge): the most familiar type. Though technically all the types listed here are suspension bridges, when unqualified with adjectives the term commonly refers to a suspended-deck suspension bridge. This type is suitable for use by heavy vehicles and light rail. The main cables are ...
Other suspension bridge towers carry transmission antennas. [49] Conservationists use wildlife overpasses to reduce habitat fragmentation and animal-vehicle collisions. [50] The first animal bridges sprung up in France in the 1950s, and these types of bridges are now used worldwide to protect both large and small wildlife. [51] [52] [53]
You shouldn't dismiss MacPherson struts, which are on more top cars than you'd think. Nearly all Porsche 911s, every BMW M3, the list goes on...
Prior to the bridge's construction, engineers had believed that a suspension span's length was a large indicator of a suspension bridge's economic feasibility, but the bridge's completion proved that longer suspension bridges were both physically and economically feasible. [35] The George Washington Bridge's total width is 119 feet (36 m). [1]
Modern formula cars that have exposed wheels and suspension typically use streamlined tubing rather than simple round tubing for their suspension arms to reduce aerodynamic drag. Also typical is the use of rocker-arm, push rod, or pull rod-type suspensions, that, among other things, place the spring/damper unit inboard and out of the air stream ...
Nowadays clapper bridges are only used as footbridges. The Kapellbrücke is a 204-metre-long (669 ft) footbridge crossing the River Reuss in the city of Lucerne in Switzerland. It is the oldest wooden covered bridge in Europe, and one of Switzerland's main tourist attractions. The bridge was originally built c. 1365 [6] as part of Lucerne's ...
