[quote=Andinista][quote=MN3]i don't understand (at all)
[quote]Direction is simply the direction of the bridle.[/quote] huh?
are the 2 graphs:
1 with a foil above the bridal attachment tang
1 without a foil
or
just 2 examples without a foil
(showing how lowering the jib attachment increases the magnitude of the force)?Edited by MN3 on Jan 09, 2018 - 03:50 PM. [/quote]
The graphs show forces with different bridle angles, the more vertical one could be the one with a foil. What matters is the angle, it would be the same forces with no foil and longer bridles. (what happens in the foil stays in the foil...)
As shown in the graphs, the net force is the oblique one, decomposed in vertical and horizontal components. Say you apply a side force at the lower end of the stay. That would produce more tension in the oposite bridle and the stay. The other bridle would reduce its tension (the new force is doing part of the job). But forces are in all cases aligned with the wires. That’s how tension works. A rigid device rigidly attached would work differently, but it’s not the case.<!-- editby --><em>Edited by Andinista on Jan 09, 2018 - 09:49 PM.</em><!-- end editby --> [/quote]
