1. The problem statement, all variables and given/known data I will attach a scanned pic of the problem, but it seems to be a basic frames problem. However, everything seems to have to many unknowns on it to solve. I feel like I'm missing something simple, but I can't seem to make any more progress. 2. Relevant equations ƩM=0 ƩFv=0 ƩFh=0 3. The attempt at a solution My attempt at a solution began with resolving the uniformly distributed load into a single force, 1050 lb. acting 3.5 feet from either side. The next step was to solve for any pin reactions that I could on the structure as a whole, which is: Reaction at A Horizontal= 918.75 lb to the left Reaction at F Horizontal= 918.75 lb to the right I got these numbers from doing ƩM=0 around point A and F. I saw no way to solve for the vertical reactions at A and F, since any moment equations would eliminate both as they are colinear, and a moment equation around any other point would leave two unknown vertical forces. So I tried to move on to calculating forces on the individual members of the frames, but every piece seems to have to many unknown forces to solve for anything. I feel like I'm missing something basic, but we didn't spend much time on frames in class and have already moved on. I haven't had any problems with other frames in this section, so I'm at a loss. Any help would be greatly appreciated!
