    Nylon-Insert Lock Nut Material Qualification

    All, Thanks for the insightful replies. A quick update on the test - I did some work to characterize the performance of a few Nyloc samples as well as some deformed-thread, Fuji, and steel insert locknuts. In the short term, the white Nylon supplier will tide us over until we can implement a...

    Nylon-Insert Lock Nut Material Qualification

    Thanks for the quick reply, btrueblood. I consulted the standard, and found some relevant information: MATERIAL, MECHANICAL, AND PERFORMANCE PROPERTIES: "10.1.1.1 Nylon Rings. The nylon insert material shall be manufactured of nylon sufficient to meet the prevailing torque requirements of...

    Nylon-Insert Lock Nut Material Qualification

    I'm working to design a test to represent field use of a fastening tool, which includes a section to simulate prevailing torque. One idea I've been developing in the short term is to use Nyloc nuts in a rundown application to provide a consistent prevailing reaction torque for the tool to work...

    The Lancet pulls a fast one

    If you're interested in considering it from another angle, try this: As engineers, and more generally problem solvers, a large part of our jobs is to consider edge cases and externalities, right? Would it be good or bad engineering to design a freeway tunnel that's only a few inches wider than...

    The Lancet pulls a fast one

    Two issues here, Swinny. I think maybe we got some wires crossed when talking about "casual observers" and the "general public". The deleted comment above rings true, in that The Lancet is aiming at as much of society as possible. However, when I mention a casual observer, think more of the...

    The Lancet pulls a fast one

    Not sure if it's the way it's rendering for me, but the caption for the figure in question simply states: Country-level cold (in blue) and heat (in red) annual raw death rates broken down by age group If "casual observers" are not part of the intended audience, who is? Only people who are...

    The Lancet pulls a fast one

    BridgeSmith has a good point here - isn't the whole point of a chart, plot, or other graphic to communicate data? Take the politics and interpretation away, and what you're left with in this case is a chart which reads differently to the casual observer and the invested one. That ambiguity in...

    Perpendicularity of surface - long edge vs short edge.

    I think the numbers refer to this, ctopher.

    Tourist submersible visiting the Titanic is missing Part 2

    @TugboatEng, doesn't the abrupt transition (from right to left) still constitute a sudden mismatch in stiffness of the combined member? I would imagine that the idea of "slimming out" the Ti lip would be to ease the transition and avoid stress concentrations, while still having a low enough...

    Tourist submersible visiting the Titanic is missing Part 2

    Greg, what might that tapering look like? In this case, might it have been mitigated by adding a gradual taper to the inside of the ring, similar to this sketch?

    prc, is the link not working for you? It does require you to create a free account and "check out" the book.

    Good advice to be sure, Pete. The 'gut feeling' is often a valuable resource. [bigsmile]

    Thanks for the responses, all. Our testing group is mostly split between my team (which is all of the specialty testing) and the automation team, who is responsible for most of the fixturing and setting up performance testing to run on automated rigs with feedback controllers, etc. I originally...

    AutoCAD Copyright

    To be safe, I would think you could just export the files in an open-source format, and use a commonly available file viewer (a quick google search yields several) to grab screenshots? This avoids any potential issues related to Autodesk's proprietary UI and rendering. Is there a reason this...

    What to expect in the field..

    Good points - to clarify, a large chunk of our testing is developmental in nature - doing the "boots-on-the-ground" work for root cause assessment. However, the remainder is either pass/fail re: design targets or benchmarking. This company is very young in terms of its employees, especially...
