An overhanging truss is used to support an end load of 66 kN as shown. The truss is made of steel (E=200 GPa, v=0.3 and =7800kg/m3 ), and each member has a uniform cross-sectional area of 3125 mm2 .

Use both analytical method and FE simulation to determine the forces in the truss members and the vertical deflection of load point C in mm when the load is applied quasi-statically. b. Run a dynamic analysis of the problem by using Abaqus/Explicit when the load is applied suddenly at the point C. Compare the results of the maximum tensile and compressive stresses in the structure and the maximum deflection at point C with those from the static analysis with Abaqus/Standard. 1.8 m 1.8 m A B 0.75 m 66 kN E D Figure 1 In your report for Q1, besides comparing the results of the maximum tensile and compressive stresses and the maximum deflection at point C from both static and dynamic loadings, you need to submit the following results: 1. An FE mesh which shows element labels and node labels. 2. A deformed shape with deformation scale factor of 10 under static loading. 3. The contour plot of U2 under static loading. 4. A table listing the axial stress and axial force of all the truss members from the static loading. 5. A time history curve of the displacement U2 at the loading point under dynamic loading. 6. The time history plots of S11 of all the truss elements under dynamic loading. Note: in order to clearly show variation of S11 and U2 with time, I suggest you set the simulation time longer than 0.2 seconds. 7. The detailed analytic solution of the problem under static loading
