Question

Q3: Bending moment and shear force diagrams were plotted for a cantilever beam of span 10 m when subjected to a uniformly distributed load of magnitude ‘w’ kN/m over the entire span, two concentrated loads ‘2w’ kN at a distance 3 m from the free end and ‘3.5w’ kN at a distance 4.5 m from the free end respectively. It was observed that the value for maximum bending moment acting on the beam is equal to (-175 kNm). Suggest a suitable value for ‘w’ based on the given data. How it will change the reaction at the support, shear force and bending moment values? By plotting bending moment and shear force diagram for the beam briefly conclude the relationship between the values for shear force and bending moment
