| 説明 | A squarish bridge that rolls on a catenary-ish curve to raise the height so that boats can pass underneath. The bridge weighting, and the track shape, means that there is no rise and fall of the centre of gravity when the bridge turns and inverts. There is only friction and momentum to overcome. The whole turning operation is done by a hand powered winch. www.thomasrandallpage.com/Cody-Dock-Rolling-Bridgecodydock.org.uk/www.youtube.com/watch?v=Nhup4qO6hgMwww.youtube.com/watch?v=lAJy5ai6E2Uwww.youtube.com/watch?v=uM_MsO_vcFYwww.dezeen.com/2023/02/28/cody-dock-rolling-bridge-thomas...en.wikipedia.org/wiki/Catenarymath.stackexchange.com/questions/74582/how-to-solve-a-dif... |
