Quote from: TimL on February 12, 2010, 12:35:14 PMI am resurecting this thread, because the question I have directly relates to Don's original post.First, Don, thank's for the original post on calculating thrust. a nice simple explanation.However, if the total load is 1200#, and you use 600 for your calculation, which results in the 707# thrust, does that mean that each rafter creates 707, for a total of 1414 axial tension in bottom member?I have been reading a lot lately on this topic, and I do find differing oppinions. please help me understand this, is the 600# used, just 'cuz thats how the formulae works??Thanks in advanceTim
