    April 2018 PE Mechanical: Machine Design and Materials

    Passed, 1st attempt here in KY.

    MD&M practice problem of the week

    I get A as well. Maybe it's just me, but I found it to be a challenging problem, but a good one.

    PE exam cbt conversion

    It looks like all versions of the Mechanical PE are still on the 2020 tentative timeline - so we've got a few years before it switches. I still think I'll try and pass the first run through though (here in 10 days).

    Good problem. Thanks for posting.

    Yes, that makes sense. I wanted to make sure there isn't some way to know the orientation without the additional view.

    MD&M practice problem of the week

    How is it known from the information given that t is the depth into the page, rather than the width (which would make I = (2*t^3)/12)?

    MD&M practice problem of the week

    I get C. Maximum stress = tensile stress + bending stress = F/A + My/I = 3000/(2*t) + 3000lb(3in)/(1/12*t*2^3) = 30000 when t = 0.5.
