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.
