Here is a problem I have to solve http://myfiles.dyndns.org/pictures/statics9-2.png The load W is 1250lbs. The force exerted by the hydraulic thing GJ is 0 which makes HF a 2 force member. What I am supposed to do is solve for the tension in spring DE I just can't seem to get an answer for this problem. In all, there are 6 variables: Ax, Ay, Bx, By, ED, and FH. So far I have tried 2 ways: 1. Create 6 equations to solve for the 6 variables. Every equation shows the sum of moments around a certain point for a certain member. My 6 equations were for the moments acting on A on ABC, where W is on ABC, B on ABC, B on BEF, E on BEF, F on BEF. When the 6 equations were put into a matrix on my calculator, the calculator could not get an answer. It gives answers like 1Ax - 18By = 1245451 and things like that; it doens't simplify it down to express only 1 variable. 2. Create 4 equations for member ABC to solve for the forces on ABC then work on BEF after. The equations were for moments acting on A, W, B and C. The equations were put into a matrix on my calculator. The calculator again could not get an answer for any variable. Does anybody have an idea on how to approach this question?
