    2nd moment of area for an arbitrary beam section

    Thanks cowski and John, I corrected the HW solutions and updated my NX tutorial to include the simplified method by sketching in the XY plane. One last question; in the Simulation-based method (creating a custom 1-D beam element using the sketched cross section, as shown at the end of the...

    2nd moment of area for an arbitrary beam section

    Thanks John, I was able to get your same results using your .prt file. Any idea why, when I draw the same section in the YZ plane, NX doesn't play nice?

    2nd moment of area for an arbitrary beam section

    Thanks for your help. Both of those methods I had already tried and was not satisfied with the results. If you can follow the steps you listed and get the same numbers that my students should get by hand (as shown in the .pdf at the top of the thread), please let me know. For the benefit of...

    2nd moment of area for an arbitrary beam section

    Hi - I'm attempting to teach my junior undergraduate Structures students how to check their calculations for the 2nd moments of area (i.e. area moments of inertia, Iy and Iz) and area product of inertia (Iyz) of beams using NX 8.5 (it's what's available through our university). Problem is, I'm...

    Best way to teach students how to create a wing model

    To answer my own (first) question, it was because my sketch was not a closed profile, i.e. there was no solid body to mesh.[smarty]

    Best way to teach students how to create a wing model

    I'm hoping to lead my university class through the process of creating an airfoil profile, extruding it into a solid body, meshing that body, and running some load simulations. I am learning the software myself, and using version 8.5 since that's what Siemens has made available to our students...
