    Travel

    Tough decision, the thing is when your foot is in the door it is really hard to pull it out again. I'm mid twenties and would really like to take some time out having got a got a few years experience under my belt now but I'm not really willing to do it with at job guarantee upon return. I would...

    Grade 8.8 or equivalent clevis pins

    Thanks Berkshire, interesting part but it would make locking limited to thread lock because of the short thread length, is it intended to go straight into a tapped hole, I'm not really seeing where this part would be used in machine design over of bolt ?

    Grade 8.8 or equivalent clevis pins

    Thanks for the responses. I think next time I will use a shackle and pin. The equipment has been manufactured for clevis pins and space is tight so I can't really change. The SF on the maximum shear force with SS for the diameter of pins I am using is more then adequate, our company standard is...

    Grade 8.8 or equivalent clevis pins

    Hi All, Is there a reason why clevis pins are not graded? I have a steel rope anchor point that I want to secure with a clevis pin but all of the ones I can find on line are stainless steel or free cutting steel with no where near the strength of graded fasteners?? Cheers

    BS EN1993-1-8:2005 design of steel joints

    Thanks creampuff, I'm using the CATIA GAS FEA package to analysis the truss as a whole structure and so the K and KT joints have been idealized to some extent. I want to cross check the member forces from the FEA against the calculated joint resistances from the standard to avoid chord face...

    BS EN1993-1-8:2005 design of steel joints

    Morning All, I'm currently in the process of designing a CHS truss with welded gapped K and KT joints. I have been referencing 'BS EN1993-1-8:2005 design of steel joints' for design guidance though have come a bit stuck. I'm looking to calculate the joint resistances but am not really sure how...

    Back to Basics FBD

    I think the time has come to get the FEA out on this problem. Ill try and let you all know what results I get on the reactions for closure.

    Back to Basics FBD

    Thanks og172. If by x-you mean the horizontal axis on my most recent sketch then no (see above). The two scaffolding tubes illustrated as pins for simplicity counter the full torsion of the couple. I agree that there is no accurate fbd solution due to static indeterminancy for this problem...

    Back to Basics FBD

    Thanks for your rb1957 and zekeman. You've both pretty much come to the same conclusion which I also agree upon reflection so thanks again.

    Back to Basics FBD

    Good points. Iv included a more detailed sketch below. P1 and P2 are actually scaffolding tubes. F3 & F4 are the pulley resultants on the bracket which are equal and opposite in direction hence the couple. I think I may have made a wrong assumption in my initial sketch where by I assumed the...

    Back to Basics FBD

    Thanks for the response zekeman. To give you some more details on the problem. All the forces are real; F3 and F4 are resultant pulley bearing forces which diverts a vertical rope horizontally then exits vertically again, so the two 90 degree turns produce a couple between the two pulley...

    Back to Basics FBD

    Thanks for the response rb1957. That was my initial pass to take moments about a single point then resolve in the vertical and horizontal directions but I found that as F3 & F4 are equal an opposite that there x & y components cancel each other out so I get F2x+F1x=0 and F2y+F1y=0 which if you...

    Back to Basics FBD

    Hi All, I have a really simple FBD problem though its been a while since I have had to do them so I was wondering if somebody would be so kind as to check my logic. FBD attached. I have a component that is subjected to a couple Tc and is restrained in two places P1 & P2. I want to work out what...

    Catia V5 not utilizing processor power on brand new work station

    Yer I thought as much. Thanks very much for the response.

    Catia V5 not utilizing processor power on brand new work station

    Version 5.20, service pack 3. I know this is not the most up to date but others in the team have found some critical bugs in the later service packs so we're sticking with what we believe is most stable and that is service pack 3.

    Catia V5 not utilizing processor power on brand new work station

    A question for people who know Catia V5 well; My work provided me with a new work station yesterday of which the spec is shown below. I need the graphical and processor power to run Catia V5. I am however failing to see the upgraded performance I was expecting, for instance multi-instantiations...
