Here is the question: For the systems in Equilibrium, find the unknown tensions and masses. a) http://answerboard.cramster.com/answer-board/image/ed663c5fcb01e8fb6c7522cf963b49f1.jpg [Broken] b) http://answerboard.cramster.com/answer-board/image/dc409314d85cd577ab9279e81977fd75.jpg [Broken] c) http://answerboard.cramster.com/answer-board/image/d24349d36430cfb757bde12ffdbca0af.jpg [Broken] For a), I found T1 = 60N, but I can't seem to find T2 or the mass. For c), I have found T1 = T3, but that is as far as I have got. Any help on the other parts? Thanks!!
