    Good afternoon professor, I need help on this question, For a straight rod with variable cross section, its cross section change function is A(x), and the Ritz method is used to find the function of deformation of the rod under action of its own weight along the axial direction.

    What is the difference between weight residual and Rayleigh Ritz method??

    • @gurmeharsingh730
      @gurmeharsingh730 3 роки тому

      The weighted residual method tries to minimise the residual (value of the differential equation when you put in an approximate value of the function you are trying to calculate [here that would be] y= a_0+a_1x+a_2x^2).
      The Rayleigh-Ritz method tries to minimise the potential energy of the system.

    • @VedanthB9
      @VedanthB9 2 роки тому

      Have you tried to use M/EI diagram to calculate the deflection? Instead of a simple bending moment diagram, try to use M/EI diagram. It may help you.

    But deflection of ssb with udl is 5/384ei wl^4

    • @MaheshGadwantikar
      @MaheshGadwantikar  5 років тому

      It's not deflection, I took for Bending moment. Methodology may be different..I think this will be the easiest method.

    • @challanag
      @challanag 3 місяці тому

      The solution obtained her is an approximation. The exact value of deflection is 5/384EI wl^4 = 1/76.8 EI wl^4. so if you wanted to extract more precise value, then displacement function needs to be considered with more x terms.

  • @MJs-85
    @MJs-85 4 роки тому +3

    10:17 not differentiate of 2 ... SQUARE of 2 is 4 :) the entire term (2a3)^2 is basically constant since you are integrating w.r.t x i guess your concept of integrating and differentiation are a little rusty :D but good effort :)

  • @darioquintanillahuayta2978
    @darioquintanillahuayta2978 3 роки тому

    It would be important that you show the positive axis for your deflection. From your solution of the deflection at point C, I assume your positive axis for the deflection is downwards.
