    Dumb question @JohnInCarolina I understand weaves in concrete and rebar in concrete, but your drawing looks like carbon tubes.  That could be interesting because not only could you improve tensile strength, but may even improve compressive and flexural strength.  How do you "firmly" embed tubes like that?

    I’m not sure it’s really all that more difficult to attach concrete to carbon fibers than it is to standard rebar, but that’s really a question that’s more about processing/ mat sci  than mechanics.

    Just landed in ABQ.  Managed to grade all but last problem on the exam.  Will finish tonight while eating dinner, probably at the Flying Star.

    @lkapigian - people were definitely eating well right there.  Impressive groceries for those in attendance. 
    Thanks @lousubcap , the randomness of potsticker sausage and brisket dumplings went well

    The ridges in the rebar plus other surface inclusions help the concrete to "bite".  Carbon tubes tend to have a smooth exterior surface, plus the epoxy they use isn't conducive to bonding.  We prep carbon surfaces a lot to ensure a good bond.

    I had to check their menu, see if it was a place I remember (it wasn't) but the opening page featured a pic of... Matzo Ball Soup?!?   Looks like it's a christmas special, otherwise they had NM-style dishes.  I need to revisit that city.

    These are made with fibers, not tubes as far as I can tell.  Typically attaining a good bond is the result of some kind of chemical functionalization if it's not structural.

    So, magic😁 I hate rebar in road/bridge construction.  Too much salt up here. Preloaded steal cable concrete beams scare me

    Is there something specific to the composition (recipe) of the concrete for use with the carbon tubes?

    I have no idea.  Like I wrote above, I don't make this stuff.  I just used it as an interesting problem in a final exam.

    Exam is all graded, by the way.  Average was just over a 72.  There will be a generous curve applied...

    Dang, 72 for average?  That is pretty high.  What was the median?

    I always enjoyed ruining curves. I kept that quiet from most the kids, but my friends knew I set the curves in most my classes.  They would ask me what I got so they knew the curve.

    Thanks for the above.  Good read to see the "going in" and the eventual pics.  A few 3 stars accepted their roles.

    Agree with the assessment of the relative value for the average.  However, given this is graduate school the curve is definitely inflated by at least a letter grade plus.  A lower level class "C" was at least a "B" in the higher ranks.  At least that was the norm many decades ago.  Nothing like taking a few graduate level course as an undergrad and "riding the curve".  B)

    I thought it was interesting that Uma Thurman wasn't even on the list for the role that she absolutely nailed.

    I can't believe I totally went into it wanting the wrong grade? You learn so much on this forum.

    Just barely.  I think a B- average is sufficient to place you on academic suspension.

    Assuming they can pass the boards.  There is definitely an extra quality check in place for MDs.
