1. The problem statement, all variables and given/known data The image is a crane. For the diagram given, find the tension in the cable and find the moment around point A. The length of the crane the dark bar is 12 m. http://img249.imageshack.us/img249/679/exqjm6.jpg 2. Relevant equations sigma m = F *D 3. The attempt at a solution I had this question on a test today and am very curious to know the answer. if someone strong in physics please solve it. I got 51 something Kilo Newton for the reaction at A. For the tension i got 46.08 Kilo newton i believe. thank you. EDIT: In my reaction/moment calculation I included the force of the cable. that being said i forgot to account for the y direction of the cable. should the cable have been accounted for?
