Use 1D axially loaded finite element to determine the displacement of D and displacement of C. The structure is fixed at left end A and right end B. Use the deflection and element stiffness equations to find the internal forces in the members AD, DC and CB. You are encouraged to check your answers using Equations of Equilibrium and Compatibility Equations like you did in ES 202 Solid Mechanics. The structure shown below is statically indeterminate. Determine the axial deflection of point D. Use E = 10.6x 10' ksi. A-l in A-0.75 in A-05 in 1500 16 4000 lb
