Deflection of Prismatic Beam With Fixed Ends and Single Load

I've been refreshing my mind with regards to solving statically indeterminate beam deflection problems. In an effort to achieve confidence over my solutions, I attempted to recreate the standard equations in Figure 1. In my problem, I changed it so that:

  • a = b = L/2
  • Ay = R1
  • By = R2
  • etc.
However, while I expected the equations to naturally spit out Ay = By = P/2 as one would expect, I got By = P and Ay = 0. Can you find Waldo in Figure 2 and 3?

Why not use the equations as written with your numbers rather than try to refactor it?

Due to my inexperience in a real engineering environment, I don't feel confident using an equation I can't even derive. Since I won't have a professor to tell me I'm right after graduation, I'm trying to figure out how to create that validation on my own so that I can provide my employer with a solution I know will work.
