- Please determine the deflection point D of the beam shown bellow by the virtual work method Note:The real and virtual systems are shown in Fig. (b) and (c), respectively. It can be seen from Fig. (a) that the flexural rigidity EI of the beam changes abruptly at points B and D. Also, Fig. (b) and (c) indicates that the real and virtual loadings are discontinuous at points C and D, respectively. Consequently, the variation of the quantity (MvM/EI) will be discontinuous at points B; C, and D. Thus, the beam must be divided into four segments, AB; BC; CD, and DE; in each segment the quantity (MvM/EI) will be continuous and, therefore, can be integrated. The x coordinates selected for determining the bending moment equations are shown in Fig. (b) and (c). Note that in any particular segment of the beam, the same x coordinate must be used to write both equations—that is, the equation for the real bending moment (M) and the equation for the virtual bending moment (Mv). The equations for M and…arrow_forwardDetermine the horizontal deflection at joint D of the truss shown in the figure by using the virtual work method.arrow_forwardDetermine the deflection at point D of the beam shown in Fig. 7.13(a) by the virtual work methodarrow_forward
