Q1: Using the moment distribution method, analyze the beam shown in figure (1), when joint (4) was settled by (3 mm) under the applied load. Use E= 200 kN/mm2 and I =10×107 mm4. (Use modified stiffness where it is found, and don't use more than three cycles of release). 20 kN 20 kN 20KN/m 30KN/m 2 6m 3m 2m 3m 6m Figure (1)

The compound beam is subjected to a uniform dead load of 380 lb/ft and a uniform live load of 285 lb/ft. Assume B is a pin and C is a roller. Follow the sign convention.
