1. The problem statement, all variables and given/known data Calculate the forces for each member. 2. Relevant equations Sum of forces in x=0 Sum of forces in y=0 Sumof moments about D=0 3. The attempt at a solution Work is on attached image of problem. I'm having trouble solving for support reactions. At D there is a hinge. At A, C, and Fthere is a roller. I know that the hinge provides a horizontal and vertical reaction force where the rollers only provide a vertical reaction force. I know I can't sum the moments about a roller and I'm don't think I can sum the moments about the hinge (did this anyways as Im stuck). So how can I solve these support reactions?
