- I would like to know if my analytical approach for the deflection of an frame is correct.

Hi all,

Currently I am working on a home-project, making a trike. Now just for fun and because I like to calculate things, I calculated the deflection of a frame with a load. The frame is shown in the picture below, I added the force for clarity.

With my analytical calculation I found a deflection of 0.016 mm, with a load of 800 Newtons. Are the following assumptions correct?:

I did a cross check in Simulation and found a deflection of 0.039 mm, how can I get a 'more' accurated analytical calculation? The difference of those two (>50%) is quite a lot, isn't it?

- Point B and C are fixed, this means L1 doesn't play a role in this calculation.
- Reaction forces at point B and C are 0.5*F.
