Have you tried an FEA model? Or are you particularly looking for an analytical solution?
If you have access to FEA you can use an energy equivalence approximation to determine the stresses in your structure under impact. You know the...
Well your equation appears to be dimensionally consistent and I get the same answer as you do when I run your numbers. Do you have any more...
How about "give 'em a shake, rub 'em briskly together and they'll be dry in the time it takes you to walk back to the bar"?
I've gone for a sequential part numbering system for my stuff. I've never really liked "intelligent" part numbering systems, possibly because I am...
It could work, but as you've found it reduces your choice of bearing type dramatically. And I wouldn't even bother trying to drill your own holes...
Why do you need to bolt the bearings to the tubes? Can you put a step on the end of the smaller tube and a pocket in the larger tube and set the...
Have a look at this paper http://escholarship.org/uc/item/2239m1ns#page-14. Maybe adjusting your depth of cut and feed per tooth (at least for...
OK I can't do that (open link menu item is greyed out) but as long as you got it, no problem. I don't have any documentation of the calculation...
Yes, that sounds plausible. You'd need to determine the sum of the moments of the forces at the points of attachment about the overturn axis to...
I take it you managed to see the picture then? For some reason I can't see it on my own machine!
Well based on your info, I got the following. The pink arrow shows your 50 tonne force and the figures the reaction forces calculated at the...
Are you looking for reaction forces at the base to determine foundation fixing sizes, or to determine loads in the frame? Can you send a sketch?
Fairly straightforward to do this with the motion analysis tools built in to many CAD programs or even with FEA. Fix the points of attachment...
I'm happy to have a look too. Cheers Andrew
That's a good thought, although you would need to run the plastic strip (not actually a cord) inside a guide channel to stop it buckling (it's...
Agreed, and that's sort of what I meant to imply by the "rubber stamped" comment.
There is no protection of the use of the word "engineer" in the UK. However, you may only call yourself a "Chartered Engineer" (CEng) or...
Mark makes some good points, and I too have given up worrying about how to explain what I do to other people. I just tell them what I produce,...
If you are looking to make yourself more employable, go for SolidWorks. There are many more installed seats of SolidWorks than Catia, and a quick...
