1. The problem statement, all variables and given/known data Find the components (a) of the reactions at E, (b) of the force exerted at C on member CDE. 2. Relevant equations Equations are on attachment 3. The attempt at a solution Okay so I am having a hard time figuring out how to obtain Reaction D without using a force triangle because that is what the solution uses. I took sum of the forces in y direction at the pipe and get 10kips but what about the x direction? RD is going to have both x and y components.
