Unformatted text preview: EA=10,000 units, while elements c and d have axial section stiffness EA=20,000 units. Use the displacement method of analysis for each load case separately to determine 1. The displacements (translations) at the free dofs of the structural model 2. The basic forces in all truss elements 3. The support reactions; use the support reactions to check global equilibrium. What happens to the basic forces of the truss elements if the section stiffness EA is doubled for all elements? What happens to the global dof displacements in this case? 50 30 a b c 8 8 6 d...
