Deliverable 1 (2 marks): Hand calculations as estimates. Consider a beam cantilevered at A, and loaded with a tip bending moment at B. Use the parameters with _SB found in Excel file "Model#.xls" as needed. Determine the deflection at the free end B using appropriate equations from strength of materials or machine design textbooks, or a mechanical engineering handbook. In addition, determine the maximum Dending stress at A.
