    What is the best engineering advice you ever received?

    This one is a bit off topic but when designing something I always remember what one of my Professors used to say: "You can't make it lighter, stronger and cheaper - but you can pick two."

    Swivel vs Shoulder Bolt

    So here's the issue: I am designing a swivel (1.9" dia OD of high strength 416 SS) the load will be retained by a 1/2" shoulder bolt that spans a .65" channel through the middle of the swivel end. Issue: I am unable to find any guidelines on how close the bolt can be from the end of the swivel...

    Shoulder Bolt Loading Question.

    Thanks for Reading I have a question on the stress analysis that has to do with a design that will be using a shoulder bolt. The bolts will be the primary loading points at either end of a vertically loaded swivel. The mounting hole for the bolt will be called out at 0.3750" (+.0015/-.0010) as...

    Slip Ring help needed

    Thanks for replying to this thread EdDanzer..Since posting the thread I might have a solution...but to answer your questions: Though I can't use the cable as a ground, I can use the swivel body as one of the conducting paths. The slip ring will have to continuously rotate but the maximum...

    Machined thread strengths

    Hello Members, I have been searching in vain for a good site that would help calculate the pull out strengths on machined threads. Just wondering if anyone has a link or other reference material on the subject. Thanks

    Machined thread strengths

    Hello Members, I am searching for a good site or reference material to help calculate the pull out strength on a threaded section that will be machined into a part. It will terminate in a Grade 8 Nut so I am not as concerned with the nut strength as I am with the machined section. Thanks
