2- A continuous beam ABCD subjected to the loading shown in Figure 2 is fixed at A and simply
supported at B, C and D. Calculate the reactions at A, B, C and D then draw the shear force and
bending moment diagrams for the beam, and showing all important values.
($I_{AB} = 175 \times 10^6 \text{ mm}^4$; $I_{BC} = I_{CD} = 350 \times 10^6 \text{ mm}^4$; $E = 200 \text{ kN/mm}^2$)
