I am building a frame that is supposed to resist the highest possible force in the horizontal direction. I am stuck at determining what is the optimal angle at which to design a member that runs against the applied load. In my project the load applied is in the - x direction and the member i am designing is in the + x and + y direction. The load is being applied by a loading bar and the force will be applied at a height of 4 in. I was just wondering how to pick an optimal angle for my member. I only have 6 in of platform to work with so I need an angle that will make my frame fit on the platform. If anything is unclear, please let me know; I'll try clarifying it.
