    Women in Engineering II

    "Which is how such matters should be resolved. So, if they get harassed or assaulted, they should "not complain about any mistreatment real or imagined?" The implication is that they will not put up with it and will take whatever steps are necessary to correct the situation. One should not...

    Women in Engineering II

    Bottom line from the report- "Statistical analysis that includes those variables has produced results that collectively account for between 65.1 and 76.4 percent of a raw gender wage gap of 20.4 percent, and thereby leave an adjusted gender wage gap that is between 4.8 and 7.1 percent. "...

    Gender Based Hiring Quotas in Australia

    The thing that always worries me is institutional discrimination. Individuals are always going to say dumb things and make disparaging remarks. Once the stated policy of an organization becomes we are only going to hire a minority female with a disability or fill in the blank- how does that...

    Seeking AutoCAD alternative that can create dynamic blocks

    All I could find on TurboCAD: "TurboCAD not only has dimensional and geometric constraints (provided by D-Cubed, the same technology used by AutoCAD), but also has a parametric Parts Script Editor, which might be the closest it has to AutoCAD’s dynamic blocks." From this review...

    Seeking AutoCAD alternative that can create dynamic blocks

    Look at TurboCad as a ACLT replacement. Contact: Bob Mayer President, IMSI/Design Cell: 415-342-1817 Office: 415-483-8068 I am not affiliated with them but when I was looking to make a switch when AC went subscription last year this one was the best replacement for LT I could find. I think...

    Why no tolerance on bearing ID/OD?

    I would add that it is not uncommon for companies to use slip fits when it is necessary for assembly or some other reason. Generally it is best to have a way to hold the inner ring (for example) axially in preload with a nut, clip, etc. Sometimes it works. It just depends on the application...

    Long bearing for 3/16&quot; shaft

    Check out a needle bearing: http://www.jtekt-na.com/engineering-tools/catalog-library/ (download the needle catalog and look on page B-2-54) I doubt there is anything 3/16" x 2". But why not put one on each end with a spacer? Any information on the speed and loading of the bearing?

    Weird bearing failure mode

    "Thanks for the ideas. This turned out to be heat treat defect in the ball. A failure that was not able to be replicated when tested with more name brand bearings. Lesson learned: Don't let purchasing source bearings just anywhere :) " I think you got it right. When we've seen this failure in...

    trying to find an engineering data management system

    Standard Catalog Bearing Quality

    Most manufacturers offer ABEC 1 as standard, however all the first world producers are much closer to ABEC 3. So buy from Fafnir, SKF, FAG, Koyo, NSK or NTN and you will be fine unless this is a specialty application like a machine tool spindle. For motor applications none of those names will...

    Minimum raceway hardness for lightly loaded needle roller bearing

    Unfortunately the Torrington catalog is not available on-line right now. Sooner or later it would be here: http://www.koyousa.com/DesktopDefault.aspx?tabid=603 The generic recommendation is for a minimum shaft hardness of Rc = 58 and a wave free surface finish of 8 microinches. Light loading...

    FBD for taper roller bearing

    See: http://www.koyousa.com/brochures/pdfs/catb2001e-4_a.pdf page A35 is very close. See: http://www.lmr.com.br/httpdocs/catalogos/TIMKEN/USA_chap_1.pdf page 4 is more detailed. Hope that helps.

    Root cause analysis of ball bearings

    "9880501843, This bearing is from a paper sheeter and it has been seleced from the OEM. When it fails, the sheeter goes offline and then our fitters oull the roll , dismount the bearing and fit new ones in. it is a rotating outer ring with a stationary outer ring load. So the inner ring is a...

    Root cause analysis of ball bearings

    I don't agree with the approach of trying to accomodate an incorrect mounting method. Also, please be advised that case hardening is not likely to solve the problem. It "might" reduce the damage but if you are impacting the bearings hard enough to brinell the raceway of a through hardened...
