Referring to Example 4.6, draw an element to show the corresponding normal stresses with respect to the y-axis on the original element

Q44;

Two solid bars made of steel and aluminum are rigidly fixed to walls A and C as shown in the following figure. At point B where the two bars are attached, T = 8,000 lb in. is applied. Determine the maximum shear stresses in the steel and aluminum bars. Assume Gst = 12 × 106 psi for steel and Gal = 3.9 × 106 psi for aluminum.
