A. Shear Diagram: B. Moment Diagram: C. Maximum Bending Moment = 80 kN.m2. A simply supported beam of length 10M has a concentrated load of 30kN 3m from the left hand end and another concentrated load of 50kN 3m from the right hand end. P1a. Draw the shear force diagram.b. Draw the bending moment diagramc. Determine the maximum bending moment in the beam.d. Determine the maximum shear force.A. Shear Diagram: B. Moment Diagram:C. Maximum Bending Moment = 132 kN.mD. Maximum Shear Force = 44 kN3.

The maximum bending moment a beam can sustain is 175 x 10 6 Nmm. If the maximum stress in tension or compression is 165 N/mm2 suggest an appropriate section beam from the table in the appendix P2Given: M = 175 x 10 6 Nmm f = 165 N/mm2 Solution: Section Modulus, Z = M / f Z = 175 x 10 6 / 165 = 1060606.061 mm3 = 1060.61 cm3 The lightest section with Z > 1060.61 is the I beam 406 x 178 with Z = 1186 cm34. A steel column is required to support a load with a slenderness ratio of less than 100.

If the column is fixed at both ends and is 3m long, suggest a suitable section from the table in the appendix. P2Effective length factor, k = 0.5 for fixed columnsL = 300 cm Since kL/r
