An unobtanium support strut (A) with a rectangular cross-section (width as shown, depth 10 mm into the page) is glued to a horizontal obsidian bracket (B) that has the same depth. A load P 13 kN is applied through the centroid of the cross-section of the strut aligned as shown. Given 0 - : 50: a. Determine the internal reactions at the glue joint between part A and part B (show your free body diagram and equations of equilibrium). b. Determine the average normal stress (0) and the average shear stress (T) in the glue joint. c. Assuming the joint will fail in shear, determine the minimum required shear failu strength (Tfail) of the glue given a required factor of safety of Nfs = 2.5. 20 mm A 0 B
