a) Draw the shear force and bending moment diagrams for the beam shown in the figure above
and determine the maximum shear force and maximum bending moment along the length
of the beam.
b) Without doing any calculations, illustrate how you would determine the shear force and
bending moment at any point in the beam by using the principle of superposition.
c) By using the method of virtual work, calculate the vertical displacement at point C as a
function of the flexural stiffness of the beam, EI.
