A steel T-section is to be used under torsion. The cross section shown below has dimension bf=6 in, tf=0.6 in, d=10in, tw=0.5 in. It is subjected to a torque at the centerline of Tx = 1,500 in-lb and the member is simply supported with respect to torsion.
A) Determine the St. Venent torsion constant J.
B) Determine the maximum Sr. Venant shear stress on each leg of the section due to the twisting moment. .
C) Explain how the warping restraint effects the stresses and deformation of the section (no calculations required).
