- TL;DR Summary
- I am trying to determine the minimum length for the base, but I am struggling with the sum of the moments equation to find the length.
Hello all-
I am trying to design a simple cell phone holder that will be printed using a 3D printer. For this phone holder I would like the base to be the minimum length possible to avoid the thing tipping over backwards. I drew a simplified slope and base which represents the phone on the stand, but I am pretty rusty on my mechanics and I think I am making some incorrect assumptions in my problem.
For the problem I am assuming the holder is rigid, the thickness of the phone is negligible, and the mass of the holder is negligible. I did not show it in the drawing but there will be a little ledge at the bottom to prevent sliding down.
I have attached my attempt to solve for the length of the base, but as you can see my solution is nonsense. Is anyone able to see what I am doing wrong?
Thank you for your help. In exchange I'd be happy to print someone a cell phone holder once it is complete. (Or any other printable CAD file you provide. Then maybe I will feel like slightly less of a mooch in these forums).
