Tutorial 3: Shear Force and Bending Moment Diagrams Sketch in good proportion the shear force and bending moment diagrams for the beams shown in the following figures. Calculate the magnitude of the maximum values and indicate their positions. Also sketch the deflection curve and indicate points of contraflexure (where M=0) if any. ( All forces are in kN and distances are in m, unless otherwise specified.) 1. 4 6 3 5 4 2 20 2. 20 kN/m 4 6 3. 30 40 40 kN/m 1.0 1.25 1.25 4.5 4. 5 5 5 3 4 3 14 5. 2x10 4 N/m 3x10 4 N 4x10 4 N 6m 2m 10m 6. 5 20 7. 20 10kN/m 1 3 8. 6kN/m 4 2 2 9. 6 2 6 3 6 6 8 24 Answer: (Distance from L.H.S.) 1. 6.7 kN from 0 to 4 m ; 37 kNm , at 10
