Homework Help: Shear Center Problem

  1. May 12, 2012 #1
    1. The problem statement, all variables and given/known data

    The problem and cross section are attached. (#2 on the PDF)

    I have to find the length of b if the shear center is at point O.

    The horizontal lines that are not labeled are of length a.


    3. The attempt at a solution

    I took the Moment about O to get the equation for e.
    I have split the cross section into 3 different sections, used tau=VQ/IT
    Took the integral of tau to get V of the particular section.
    I then found I total.
    All of these values are respect to t,b, and a.

    After I've done all this, do I set the e=0 and solve the equation for b in terms of a and t?

    I am not sure if I am doing this right.
    Will post the work I've done if necessary.

    Thanks!
