Finding Stresses AND Factor of Safety Calculations on 3D jig
Finding Stresses AND Factor of Safety Calculations on 3D jig
(OP)
Hello,
I had an interview where I had to figure out the FOS at the point where the jig was most likely going fail. Didn't get all the way through the problem and didn't know if if i started out the problem correctly. Could I get some help with working through the problem? The attachment has the information given in the problem that I can remember.
Thanks,
Reuben Huddleston

do they really need 5 decimal places ? maybe for tooling, but ??
that's a lot for an interview calc !
i'd look at the two ends of the inclined flange.

Thanks for responding! No they didn't ask for 5 dec. places that was just my settings in AutoCad

where would you analyze the structure ?

point B or A sure ... there's a subtle difference between the two. The moment at A is clearly higher, but ...

I suspect section C will have the highest margins, and so therefore not critical. Just like a tension failure in the green web area isn't likely to be critical.
Section A has the higher bending moment, but there's a twist in the calcs that makes it stronger than section B and so it isn't really obvious which is critical.
