Hi all,
I am attempting to design a large ached bridge with technic parts, and this
means I'll need plenty of reading on the subject of beam-geometry. Can any
of you guys help me out in my research?
The thing that is giving me the biggest headache so far is the relation
between angles possible with LEGO beams, the only sure stuff I know is the
famous 3-4-5 triangle and that is not much help for this :-(
My ultimate purpose is to design in LEGO something that ressembles either
one of the two mettalic bridges in the following link:

Thank you very much for any help you can provide,
Pedro

| (...) Pedro, I found it easier to think in terms of beam length, rather than angles. If you have a good profile view of the bridge, one way is to overlay it with graph paper (or just use a ruler) to measure the beam lengths, then match them as (...) (22 years ago, 4-Jul-02, to lugnet.technic)

| (...) ROSCO is right, you should think in terms of beam lengths. Your thought process should be similar to how it's actually built. In other words, you build your beams in certain lengths first and then put them together to form the bridge. The (...) (22 years ago, 4-Jul-02, to lugnet.technic)

| (...) Pedro- This may or may not be any help, but when I built my 4' swing bridge ((URL) I had never built a technic bridge before. All I did was employ a little trial and error. So I guess my comment would be that a prior command of beam-geometry (...) (22 years ago, 4-Jul-02, to lugnet.technic)
