Mathematicians Bridge (English Mathematical Bridge , also Mathematical Bridge ) is the slang term for a wooden pedestrian bridge on the grounds of Queens' College in Cambridge . It spans the River Cam and is officially referred to simply as the Wooden Bridge (German: "Wooden Bridge").
history
The bridge was designed by William Etheridge and built in 1749 by the builder and architect James Essex . In the years 1866 and 1905, it was rebuilt according to the original plans. Although it has the shape of an arch, the structure consists entirely of straight wooden beams and boards.
The Old Walton Bridge, a wooden bridge also designed by William Etheridge based on this principle, spanned the Thames in the county of Surrey in the 18th century .
Mathematical Aspects
The wooden beams form a series of tangents that indicate the arch of the bridge. Radial struts fix the beams and make the construction rigid and self-supporting. This type of arch construction was also used for the falsework when building stone bridges in earlier times . The tangential beams function almost without exception as supports, while the radial components are under tension. This results in only a very low bending load.
