An aluminum alloy [E = 10,300 ksi] tee‐shaped bar is used as a beam. The cross-section of the tee shape, shown in the figure below, has a total depth of d = 7.5 in. The centroidal z-axis of this cross-section is located 2.36 in. above point H. The beam spans in the x-direction and it bends about the z centroidal axis. A strain gage is affixed to the side of the tee stem at a distance c = 1.25 in. below the top surface of the tee shape. After loads are applied to the beam, a normal strain of ɛx = −810 μɛ is measured by the strain gage. What is the bending stress at point H?
