Beam : Is the most common bridge in the world 
Truss : A framework, typically consisting of rafters, post and struts.
Arch : A bridge with abutments at each end shaped as a curved arch. 
Cantilever : A bridge in which each span is constructed from cantilevers built out sideways from piers.
Suspension : A bridge in which the weight of the deck is supported by vertical cables suspended from lager cables.
Cable stayed : A bridge in which the weight of the deck is supported by a number of cables running directly to one or more towers]]> 2017-05-02 21:29:03 UTC https://padlet.com/99033253/humpydumpydromedary/wish/169550536 Role of Forces in Bridges 99033253 https://padlet.com/99033253/humpydumpydromedary/wish/169550537 By Conner
Arch bridges-
Compression, reaction, and tension forces are the 3 main forces in an arch bridge. Compression is used in the arch itself. When a heavy load passes over it, it distributes the weight evenly to both ends of the arch. At the same time, reaction forces push upwards along the arch, and tension holds the main, flat part of the bridge secure.

Truss bridges-
Truss bridges are bridges made up of a metal frame of triangles. These Bridges are supported by the strength of triangles as opposed to the strength of squares are rectangles. Squares can be changed into a parallelogram with collapse triangles are stronger and can support more weight. When a heavy load passes over a truss Bridge, the weight of the truss bridge is passed into the shapes of When a heavy load passes over a truss Bridge, the weight of the load is supported by the sheer strength of the triangles in the frame.

   Bridges began as primitive, makeshift platforms made of anything lying around. People used logs, vines, and stepping stones to cross chasms and rivers first.When the first modern civilizations came to be, bridges began to be made and used.
   They were, again, very makeshift until Roman times. The Romans invented mortar, allowing them to build more structurally integrate bridges. On the topic of advancement, the first cast iron bridge was erected in 1779. During the Industrial Revolution, cast iron was replaced by steel. Steel is stilled used today in bridgemaking.

Tied Arch Bridges-
The main force in a tied arch bridge is tension. The bridge has an arch hanging over it with cords stretching tightly down. These cables produce a high amount of tension that supports the bridge. As a heavy load passes over the bridge, the tension in the cords holds the bridge secure.

Cantilever Bridges-
The 2 main forces in a  bridge are compression and tension. Tension acts on the top half of the supports, which pulls up on the arms supporting the weight of the load. The arms are in  compression force, which pushes the pieces together.

Suspension Bridges-
The main force in a suspension bridge is tension. Suspension bridges have big towers that go deep underground to help support the bridge. Cables are attached to these towers and the bridge, producing a high amount of tension. When a heavy load paces over the bridge, the tension in the cables increases to hold the bridge.

Beam Bridges-  
The forces in beam bridges include compression, tension, and reaction. When a heavy load passes over a beam bridge, compression forces push inwards towards the load while tension forces push outward away from the load. Reaction forces push upward along the poles supporting the beam bridge to keep the bridge from collapsing.
