The cross-section of the thin-walled beam is axisymmetric and described below. The beam is
subjected to the vertical force (25 kV) acting downward.
Provide answers to the following questions:
a) Find z-coordinate range in which maximum shear force ($V_{max}$) occurs in the beam (5 pts).
b) Calculate $I_x$ (10 pts).
c) With $V_{max}$, draw shear stress distribution in the cross section diagram with value of shear
stresses at point A, B, C, and D(25 pts).
d) Find shear center distance from D and indicate it on the cross-section section (10 pts).
