Hi guys, I'm a mechanical engineering student and my dad want's a simplified motorized rotating table. I want to take it as a chance to implement my study in it, and i'm doing it all the way modeled on solidworks and animated. The calculation part is holding me back, there's a couple of things I need your help with :-) In the attached picture (sorry, haven't started modeling the thing yet): http://s13.postimage.org/43lpw52rb/image.png 1. on each sector of the table, which you see divided to eight, 45 degree parts, is a weight with mass M1 with a C.G distanced R from the center of the table. How do I calculate the minimum thickness of the table (in general, material will probably be aluminium) before the load passes the yield strength of the table? 2. regarding the last question, I would also like to know how to calculate the strain of the table in a given material and thickness (t), and see if it passes 1% ? 3. It's kind of simplified but the table is sitting on a bearing on top of a stationary axis and legs who support the weight. Given that the axis is a pipe with diameter D0 and thickness t2, how do I find what should be the pipe's dimension in order to support the weight of the table and loads on top of it without yielding? Thank you guys so much!
