The 2D frame introduced in InClassHandout01 is made of members that have a rectangular cross-section of 16 inches \( \times 8 \) inches. The frame as well as the perpendicular section at the mid-point of \( A B \) (Section (a)) are shown in the figure below. Determine the average normal and shear stresses \( \left(\sigma_{a v g}, \tau_{\text {avg }}\right) \) produced due to the internal normal and shear forces \( \left(N_{x}, V_{y}\right) \) calculated at Section (a), and enter the magnitude of the shear stress in psi correct to 3 significant digits below. You may use the values of the internal normal and shear forces that you would have calculated as solution to part (a) of the problem in InClassHandout01. jection (a)
