Q1: A cantilever beam having span ‘L’ m was subjected to a uniformly distributed load of
magnitude 8 kN/m for a distance of ‘0.6 L’ from the free end and two concentrated loads one of
magnitude 15 kN at a distance ‘0.25 L’ m from the free end while the other of magnitude ‘22’ kN at
a distance ‘0.6 L’ m from the free end respectively. It was observed that the maximum bending
moment acting on the beam is equal to (-369 kNm). Suggest a suitable span for the beam based on
the loading condition. How it will change the reaction at the fixed support? What happens to the
shear force and bending moment values at the fixed support, free end and at the center of the
beam? By plotting bending moment and shear force diagram for the beam briefly conclude the
relationship between the values for shear force and bending moment.
