Q2. In the illustrated wood-to-wood joinery assembly, an inclined compression member imposes an axial force of 600 lb acting along a 3:4:5 slope. Assuming the contact interfaces are frictionless, evaluate the normal stress distribution experienced at the vertical step AB, the normal stress distribution at the horizontal seat notch BC, and the average horizontal shear stress acting along the failure shear plane extending from the internal corner back to the free end, DB.
