Question

Problem 1 -

When shear force S_y is applied to Web 24, calculate:

a) Calculate I_xx for the x-axis using a thin-walled section approximation.

b) Calculate the distance to the Shear Center (e).

c) Calculate and plot the shear flow distribution (q(s) or q(Θ)).

d) Calculate the maximum shear stress and find the location.
