mathematical bridge

By Sergio and Max

The bridge type is timber truss bridge and the structural system is self-supporting truss system composed of straight beams, which distribute weight efficiently

The Mathematical Bridge is a wooden footbridge at Queen's college, in Cambridge, spanning the river cam. Famous for its precise engineering and unique design, it appears as an arch despite being constructed entirely from straight timbers. Built in 1749 and reconstructed in 1905, it remains an iconic symbol of Cambridge's architectural and academic heritage.

Main frame: straight wooden planks form a truss system, creating one ilusion of a curve bridge Joints and fastenings: the wooden planks are connetced each one using iron bolts to secure the bridge Supports: stoneabutments at both ends archor and distribute its loads to the ground Decking: a wooden walkway to allow people to cross the river through the bridge

Dimensions: Lenght 15 meters, Wigth 3 and Height 2.5 meters Cost: between 250.000£ and 500.000£ Time of construction: between 3-4 months Name of contructor: William Etheridge

Compresion: at the beggining of the structure and in the endTension: in the entire building with the cables supporting the wooden planks
