2. A continuous beam ABCD is carrying uniformly distributed load of 5 kN/m as shown in Figure 2. Compute reactions due to the following support settlements:
Support B 0·005 m Vertically
downwards Support C 0·010 m Vertically downwards
Assume E =200 GPa and I 4 x m^4.

3. Analyse the continuous beam shown in Figure 3 by Force method. The beam rests on elastic supports at B and C. The flexibility of supports B and C in t-m units are 10/EI and 25/EI respectively.
