    Pulley & Winch Reaction Loads

    ADAMS https://hexagon.com/products/product-groups/computer-aided-engineering-software/adams is overkill for this. You should be able to do it by hand quickly.

    Shaved CSK NAS1097 rivet strength allowables

    It won’t get funded unless one can somehow link in nano and AI.

    Typical Details

    lex - that “met budget” approach sounds exactly like the “lets outsource engineering to low cost labor countries” approach that has become prevalent in other industries.

    strain in plastic hinge

    Seems like the formulas should include section properties for the beam, and the stress-strain curve for the material

    Manager Says Keep the Restraints — I Think They’re Unnecessary. Who’s Right?

    AlphaSpace - to be blunt, why are you not discussing this in detail with your manager? rather than with a bunch of random (though probably skilled) people on the internet? What is your plan - tell your manager than you approved the change based on internet advice?

    results of tests as per SA-480

    I would expect actual test values for individual specimens.

    Mesh singularity on non-manifold geometry

    that is likely the cause of the stress peaks at the spar web at the root. but you have two lugs at the root of the spars. how exactly are you modelling that area? note: you are unlikely to get accurate stresses in those lugs with the current mesh refinement, and since the stresses in the lugs...

    JetZero Blended wing proposal

    oh they will eventually ask the US govt for more $, like any good R&D project. and its just a demonstrator. building a certified design and getting it into actual production is WAY harder and expensive.

    Subdivision Work - Pricing

    OP - why not ask the architect what his fee schedule is?

    SpaceX Starship missions

    those LH2 tanks leaked.

    Splice Theory Question

    there is also shear transfer due to the moment. resolve the moment into a tension / compression couple at the centerlines of the two thinner sections, then transfer that load across the joint in shear.

    Thread embedment required for bolt in tension

    the general rule of thumb is min of 3 full threads. and the nut material/type needs to be strong enough to fail the bolt in tension.

    Prying Action Plate Bending (AISC)

    well what is your definition of "any"??? nothing is perfectly rigid. well, what is "some"? a sketch of this plate, with applied loads (a balanced fbd) and boundary conditions / connections would greatly help.

    Coaxiality tolerance for the welded structures

    is there a hole in the plate with diameter equal to pipe ID? what is the application? where did the drawing come from? if it came from a customer of yours, then contact them and discuss the requirements

    Coaxiality tolerance for the welded structures

    what is the issue? the tolerance looks to be on the left hand side, referencing datum A shown on the right.

    viscoelastic behavior + Damage

    then with displacement controlled tests, you will see load drops in the response curve which will not show up in a load controlled curve. these load drops are an artifice of the displacement controlled loading, as when there is a stiffness drop (due to damage, etc) there will be a load drop and...

    viscoelastic behavior + Damage

    was the test conduced a load-controlled or displacement-controlled?

    Fatigue justification of a thread bolt

    1) suggest you delete and repost in the Aircraft Engineering forum 2) can you show a sketch of the joint? 3) is the bolt threaded into the fitting? (I hope not) or a thru bolt with proper nut/collar on it?

    Tria/Tetra vs Quad/Hex

    3 node triangles are not good. 4 noded tets are very bad. avoid both. auto meshers create triangles/tets because it is "easy". grrrrrr.

    Air India 787 crashes on take off

    wrong. was GE engines.
