s a pretty good manual on their website, http://twl.uni-ak.ac.at/karamba/download/karamba_manual_0.9.07.pdf which has an introduction to BESO in it I am pretty sure. …
uegwSbkICABw&ved=0CAYQFjAA&client=internal-uds-cse&usg=AFQjCNH14SMyxo4UkC_6ghKKGi2Wsqb3Ng ) I managed to solve the 3rd point! can someone help me out with the 1st and 2nd…
t SpreadsheetQuery is unscriptable when it gets to line 20 when I try to set the q['title'].

e vertical load V = q * l/2 and the sum-vector of H and V points in the tangent direction of the cable (as zilic mentioned before).
For example:
The wight of the wet fabric q = 4 kg/m == 0.04 kN/m, l = 2 m and you choose f ~ 0.20 m, then
H = 0.04 * 2^2/(8*0.2)= 0.10 kN and V = 0.04 kN
If you reduce f to f ~ 0.05 m (5 cm) then H will become 4 times more > H = 0.40 kN, V = 0.04 kN
The formular is a very good approximation, but it does`nt include the elongation of the cable itself. If you want to be exact, you have to add df (due to the elongation of the cable under load) to f (the sag of the cable without load) and, of course, you have to add the wight of the cable itself to the wet fabric load too.
