Simple statics question

  1. May 27, 2010 #1
    Okay, so I am trying to understand the method of sections so I can finish my homework. I look at http://en.wikibooks.org/wiki/Statics/Method_of_Sections" [Broken] and for the life of me, I can't understand why at the bottom of the page it says Fy=0=2T2 - 981 .

    Where does the factor of 2 come from? Why not just T2? I feel like I am missing something completely obvious. Sorry for the poor notation.

    I am posting this here because it is not my homework problem, and there is no work for me to show. I would just appreciate an answer, so I can do my homework. I'm totally missing the bus on this concept right now....
