Hi, im really stuck here. My problem is with determining the support reactions. I understand that this needs to be done first before working on each truss member. But I don't understand how to determine them. I have read and re-read all my available text and still stuck. The question I can't solve, " Determine the force in each member" of the attached. Each joint are pin joints. Can some one please walk me through this? Regards Mikel <- Edit -> I have tried to solve rather than just ask, i'm aware that the 3 laws of equilibrium apply for the reactions, sum of x =0, sum of y= 0 and sum of Mc = 0. I just don't understand 1. Where the reactions are and 2. how to determine them?
