I did a back-of-the-envelope calculation today for a 10 m long pipe,
15cm in diameter, half filled with liquid, sitting on 1 support at each
end. When the pipe is tilted by 1 micro radian, the difference in
loading between the posts is the equivalent of around 3 or 4 grams.
Could this be approached by monitoring the loading on the supports?
