1. The problem statement, all variables and given/known data Solve for the support reactions (at A and B) in the figure given. (the pink thing is a cable and there's an arbitrary weight hung at the end of the cable). 2. Relevant equations sum of forces in y direction=0 sum of forces in x direction=0 Sum of moments =0 3. The attempt at a solution I tried solving this using the method of joints in TRUSSES. However, consider point A (JOINT A). Here, there's the vertical component of support reaction and no other vertical force to cancel this, so joint A is not in equilibrium. Why does the method of joints not work in this case??? My professor told me that Truss analysis doesn't work in structures that are not 2 force members...however, I find many contradictions to this. Please give me a solution to this problem.
