Are there any general rules of thumb for which to choose? I have a lot of ambigous HW problems which don't specify, they just list a safety factor. For example, if I have a mass hanging on a metal wire with a specified safety factor, then I mean it will buckle at the yield strengh but only rupture at the ultimate strengh. Is it really just discretionary?
