Hello,
I am preparing for the PE exam in 2 weeks and have some fundamental questions I would like to ask, starting with bolt stiffness. Many of these questions I know how to calculate, but I have been putting off understanding the "deeper" logic until now. Thanks in advance for your responses...
I am wanting to understand the difference between J & Ju. I understand that Ju is the unit polar moment of inertia and it must be multiplied by an area (throat for example) to calculate the stress at that point. I am good with the throat area derivation.
The way I am thinking about it, if you...

Hello All,
If you have a minute, can you suggest how you would go about creating the attached file in Pro E?

I created a xsec view in the view manager in the model and saved it as XSec "A".
When I go to place a new view in the drawing, I dont have a problem setting it up, and it does...

I have two questions on creating holes in a part with PRO E:
1) When you are giving the distance from a feature on a part to give the coordinates for the axis for the hole (x,y, or whatever) why does PRO E round off decimals...ie if i need the hole .0625" inches from say an edge, why does...
PLEASE HELP!!
i am under a major time constraint to finish a project, and PRO E is not cooperating (i guess just murphys law in action!!).
