2. (a) Figure 2 shows a beam of 14 m subjected to a uniformly distributed load of w acting on span BC and two concentrated moments of Mr and M2 at points A and D, respectively. Flexural rigidity of the beam is El. Given E= 210 GPa and I = 175(10) mm, calculate the slope of the beam at a points A and D and the deflection at midspan of BC. Use virtual work method. 5.5 KN B 9.5 kNm 8 kNm * 9 m 3 m Figure 2 2 m
(b) If the maximum deflection of the beam shown in Figure 2 is to be determined using the method of virtual work, explain the procedures of the analysis without performing any calculation. Comment on the method of virtual work as compared to the geometric approaches such as direct integration method, moment-area method or conjugate beam method in determining the maximum deflection of the beam.
