You could resolve force F to be 2 vectors one parallel to AB & one at 90 degrees. The library routine actually provides me with the X & Y components; I have to combine them to derive the resultant vector. The parallel force F' can be ignored as it's just trying to stretch/compress the link AB, the other, F'', provides a turning moment around B. The problem with that is it implies that the two components of the force can be applied separately; but that doesn't work. For example, if you applied them in the other order, the turning moment followed by the parallel force, the result is different because after you've applied the turning moment, the parallel force is no longer parallel :) With the rise and rise of 'Social' network sites: 'Computers are making people easier to use everyday'
