There are three supports at point B, C, and D along a beam. The beam is subjected to a distributed load, q of 12 kN/m and a point load P of 1000 N as shown in Figure 2. The beam has modulus of elasticity, E of 1 GPa. Determine: i. The assembled stiffness matrix. ii. The slope and deflection at the ends and midspan of the shaft. 188 B Figure 2 2.88 [8 marks] [Total marks: 10 marks]
