The figure shows a C-profile with height 2a, width a, thickness t and constant elastic modulus E0. The cross-section is initially loaded by the shear force component Qz = P.
a) Find the location of the elastic center C and determine the relevant moment(s) of inertia.
b) Determine the distribution of the shear flow q and find the magnitude and location of the maximum shear stress τmax in the cross-section.
c) Determine the distribution of the shear flow for the load case Qy = P and Qz = 0.
d) Find the maximum shear stress for the load case in c).
e) Find the location of the shear center A
