A hour’s walking around the more interesting parts of Cambridge … we loved near hear for 20 years but it wasn’t until recently when visiting after 20 years away that a camera came into the equation. You never look properly at the places you live in. Very interesting city indeed.
The Mathematical Bridge
Connects two parts of Queen’s College across the River Cam. (Quote): Originally used to create the temporary formwork used in the construction of London Bridge, the arch describes an arc of a circle. The main members lie tangent to this circle and their arrangement is designed to ensure they are in compression only with very little bending moment. The connections between these main members transfer compressive stresses. The radial members are fixed normal to the circle of the arch and they support the top rail as well as making the bridge lattice into a more rigid structure. The bridge deck is then attached to the bottom of the radials near the intersection of two tangents.
The Corpus Clock
The “Perpetual’ Clock on the wall of Corpus Christie College – hard to photograph due to an excess of Asian smartphoneographers. Fascinating thing – find out more at https://en.wikipedia.org/wiki/Corpus_Clock
