Question of the Day (01/06/2018)

Structville daily questions
From now henceforth, Structville will be publishing daily questions on different aspects of civil engineering. You are expected to enter your response in the comment section. At the end of every week, exceptional participants will stand a chance to win some gifts. This exercise is open to participants all over the world. Happy new month to you all.

Today's Question
What is the deflection at point 2 of a structure if diagram (a) is the bending moment due to externally applied load, and (b) is the bending moment due to vertically applied virtual load at point 2? (The main bending moment diagram is obtained from equation of the form, wl2/2)

Thank you for participating in exercise today, remember to enter your answer in the comment section. The main aim of this exercise to stimulate knowledge of structural analysis on the internet in a fun and exciting way. We are always happy to hear from you, so kindly let us know how you feel about Structville.

    M.dM/2EI= 6 X 2/2EI = 6/EI
    B) 6/EI metres

  2. B (6/EI metres). From wl^2/2, w= 3kn/m. From wl^4/8EI, ∆= 6/EI metres

  3. From diagram a) wl^2/2= 6kNm then w= 3kN/m and W= 3kN/m ×2m= 6kN
    Deflection in b= WL^3/8EI = 6×2^3/8EI = 6/EI hence B) is correct.

  4. From the hint,
    Bending moment=wl^2/2
    Hence, if BM=6KNm from diagram then
    From deflection formula fr a cantilever, ∆=wl^4/8EI
    ∆ = 6/EI.
    Option (B) is correct


  5. • Thanks for taking the time to discuss this, I feel strongly about it and love learning more on this topic. If possible, as you gain expertise, would you mind updating your blog with more information? It is extremely helpful for me.
