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 $\frac{?}{EI},$ where the constant has units of $N{m}^2$ or $(kN{m}^2)$ for slope or $N{m}^3$ or $(kN{m}^3)$ for deflection.

Write answers in the space provided below and submit this page, along with a cover page and all

workings attached.
