For the beam in Figure 1, use the method of virtual work to determine the slope at points B and C, and
deflection at point D.
Assume that the flexural rigidity is constant and equal to EI, i.e. your answers will be in the form
constant/EI, where the constant has units of Nm² or (kNm²) for slope or Nm³ or (kNm³) for deflection.
