Consider the cantilevered beam with a trapezoidal closed thin-walled cross-section ABCD shown in the figure. The beam is subjected to a point load of 10 kN acting at its free end at the point A of the cross-section.
Using the mid-line geometry of the cross-section, determine:
a) The maximum shear stress developing in the thin-walled cross-section due to torsion
b) The maximum angle of twist in the beam if the modulus of rigidity is 27 GPa .
