Unformatted text preview: ME 211 ADDITIONAL HOMEWORK QUESTIONS 1. Figure P1 shows a solid cylindrical shaft of diameter 10 mm and length 1 in, which is built into a wall at one end A. At the other end B, a load of 10 kN is applied at the top and perpendicular to the wall. Also, equal and opposite loads of 5 kN are applied parallel to the wall at the top and bottom as shown. Find the maximum shear stress in the beam. 10mm 5kN 10 kN 5 kN Figure P1 2.
