    Look at you learning engineering during the holidays - go you!

    I appreciate your tutorials man. But the background music should've been kept a little low...helps in focusing more on the processes 😅

    Never seen this method before in any text books. It is so easy to follow and very interesting! Can you please refer a textbook that used this method. Thanks!

    I love this method. not trying to be that guy but........what if you were going to add two plates? would this method work (i.e. thinking about Q from the plates perspective) iteratively? So do one plate, then the next

    Can the shear flow formula VQ/I be used to calculate the shear flow on the weld of 1.5”x1.5” bar to the top of the flange if it is discontinuous with a gap?

  • @kylegirouard9335
    @kylegirouard9335 Před rokem

    I have to ask, what software/application are you using. I think this could be useful at the office rather then using pen and paper. Thanks for the great video!

      I using Microsoft one note with a ThinkPad touch screen. that's it! I am starting to use this set up at work as well and really liking it

  • @MARV3L3DGAM3R

    How do we know to use the shear flow equation from the problem statement? Is it because there is a connection?

    • @Kestava_Engineering
      @Kestava_Engineering  Před rokem

      when adding 2 shapes together to create one, and then put that member in bending, the stresses are shared through the combined member through shear flow.

  • @WG-ft6tz
    @WG-ft6tz Před 9 měsíci

    Hello, thank you for the detailed description. Wouldn't the first step include verifying that the LRFD shear capacity of a W18x50 is 192 kips? Well exceeding the max design demand of 40 kips. Reviewing the answers, it may seem obvious that the intent is to check shear flow. However suppose option (D) read 'the plate is not required ' Some engineers would be inclined to check the shear capacity first before anything else, noting that the question doesn't specifically state residual shear.

    Is this the parallel axis theorom applied to the I Mom of Inertia)? Pardon the question if you stated this/.

  • @SirPoofyPants
    @SirPoofyPants Před rokem

    Is this just the weld required to transfer vertical shear in the built up shape or is this the same approach used for confirming moment capacity of the built up shape?

    • @Kestava_Engineering
      @Kestava_Engineering  Před rokem

      you know... im not sure. I know this analysis determines what connection capacity is needed to sufficiently support shear stresses throughout the built up shape but dont know if it confirms moment capacity to the built up shape. I would assume yes, as you typically always check shear flow using the maximum shear demand on your system, which relates to your max moment demand. Maybe you can give me your understanding?? great question! Although - thinking of WF beams I kind of change my mind as primarily the shear stress is local to the web and a strong connection to the flanges possibly wouldnt be required to achieve the members moment capacity. hmmmm

    • @SirPoofyPants
      @SirPoofyPants Před rokem

      @@Kestava_Engineering I've seen one example where you have to provide enough weld to fully = AsFy of either shape so that it can fully develop tension/compression capacity before weld failure, but I always feel that's less efficient.
      I occasionally have to reinforce an existing W-beam with a WT to the bottom and can never find a good example to follow... There's also the question of how differing materials of steel affect the situation too

    Hey Rich, I am in Ohio. Just curious, do you have to pass the PE exam before taking the SE exam?

    • @Kestava_Engineering
      @Kestava_Engineering  Před rokem +1

      Its different state to state but I believe there are states where you can just jump straight to taking the SE, and then need to meet a few other requirements such as experience under an SE.
