What are the physical requirements of a bridge? There are four main types of bridge, the Beam Bridge, the arch bridge, the Cantilever bridge and the suspension bridge. When building these bridges there are many factors that have to be considered before building commences. There are a number of physics concepts that have to be applied in order to build the bridges, these are the material used and the forces acting on the bridges. The two most important forces that can act on a bridge are compression and tension. Compression is a force that acts to compress re shorten the object it is acting on. Tension is a force which acts to expand or lengthen the thing it is acting on. If either or both of these forces cannot be handled by the bridge then there is a risk of it buckling (if compression is the case) or snapping (if...
