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.
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.
