    I come over just want to see if you are been well recently. I took the statics classes two years ago and get A+ in my class. You are my best online professors!! Best wish from Berkeley !

    I love when you say, "What does the box weigh?" professor :)
    also, the calculator voice was lots of fun.

    DR. Hanson, thank you for another detail explanation of Friction Slipping Tipping problem in mechanics one. These problems continue to be heavily Free Bodied.

    Wonderful Statics lessons!! really taking the time to explain the problems along with a good sense of humor :))

    doesn't the center of mass have to be adjusted for the crate and the cart (.92 vs .95) since the cart has mass

    • @silencerrh
      @silencerrh 4 роки тому

      I agree- I think there should be two mass forces for the moment equation.

  • @ahmadmustafa2151
    @ahmadmustafa2151 Рік тому

    If we want to consider the wheels, the box, and the cart (rectangle) as one body, we must calculate the center of volumetric weight of the body or we deal with the weight of the two bodies as a separate force(If we neglect the weight of the wheels) and not as a resultant correct me guys if i am wrong👍

  • @woodwright2127
    @woodwright2127 4 роки тому +1

    Good video. I like your down to earth style. Thanks for sharing your knowledge. But shouldn't the cart & the crate be considered separately, because the crate is not centered on the cart?

    im sorry sir, for situation 4, shouldn't it be 359.7? cuz -686.7(.55)/-1.05= 359.7 N
    btw thank you sir, it helps a lot and easy to understand

  • @nithishbharathi6183

    we consider friction in the roller while rotating in example 1 of your, lecture but neglecting it in roller b. why?

    • @באז
      @באז 11 місяців тому

      I think(but i might ne wrong) that when he says that the roller at point a is locked he meant that friction ONLY applied at point a and not at point b

  • @MuhammedTigrek
    @MuhammedTigrek 4 роки тому +1

    at 8:50, why isn't the reaction force 'By' included in the friction equation?

    • @2011jdp
      @2011jdp 4 роки тому +1

      Because only wheels at A are locked whereas B is just rolling freely.

    • @stanleylebrun6160
      @stanleylebrun6160 4 роки тому

      I think since they just replace Ay as a normal force "Na" it's not in the ground the friction become opposite to P.

  • @nathanlin1723
    @nathanlin1723 3 роки тому +2

    Dr. Hanson, since the crate is not perfectly center on the dolly wouldn't the moment distance for both crate and dolly should be calculate separately for situation 3 & 4?

    • @osakweolorchukwu.i9351
      @osakweolorchukwu.i9351 Рік тому +1

      Yes I was also thinking so, what made me come to the comments. I solved that way and got 195.55N for P when cart slides and 378.4N when cart tips

    @Jeff Hanson, Please make a video about C shape columns. And how to apply Secant Formula to find the eccentricity of the given load (given that the eccentricity is on the X-axis) with a numerical problem.
    This is actually the question (problem- 1139. Capter-11) from text book of "Strength of Materials (4th edition) by Ferdinand L. Singer and Andrew Pytel.

    Heeyy Professor Hanson, thanks for this video. Has really been helpful. Why doesnt By have a friction component?

    • @ryanpitre1593
      @ryanpitre1593 3 роки тому +2

      Because at the start he states only wheel A is locked, wheel B is rolling

  • @stanleylebrun6160
    @stanleylebrun6160 4 роки тому

    What happen if you can only come up with some scenario but not all of them? I feel like the should a short cut to do it quickly.

  • @NorfatimaHAli-cs2lw
    @NorfatimaHAli-cs2lw 4 роки тому +1

    hello, how come that the cart and the crate will slide when it locked at point/wheel?

    • @AzharKhan-cy5kt
      @AzharKhan-cy5kt 3 роки тому

      because it's not locked only brakes applied on the wheels
