Calculating forces ... vectors etc??? Hi all, I need to figure this out but I also need answers. I'm a tree guy and our fields cross paths in many instances when coming to rigging forces. In this diagram I have substituted a leaning tree for a steel beam which has a swivel under it so it can fall where-ever it wants. I need to know what force would be on guy wire A or guy wire B ... dont worry about the other guy wires just make like the thing is perfectly balanced in the other planes. The idea here is we use side rope techniques to fell leaners like that and it would be good to know what amount of force would be put on those side ropes. So besides getting a flat out answer which would be good I also would like to know how to work this out for future trees. If this has already been explained somewhere etc I appologise for duplication and welcome your pleasant directions.
