Construct the reduced stiffness matrix of the shown truss, Fig. 2, then model the problem using suitable element type in ANSYS Mechanical APDL software, (With Screen Capture Step by Step) then, answer the following questions: 1- Determine the nodal displacements for each joint. (10 Marks) 2- Determine the nodal forces in element 3. (10 Marks) Take: \( \mathrm{L}(1)=\mathrm{L}(2)=2 \mathrm{~m}, \mathrm{~L}(3)=2 \sqrt{2}, \mathrm{~A}(1)=\mathrm{A}(2)=\mathrm{A}(3)=80 \mathrm{~mm} 2 \), and \( \mathrm{E}=200 \mathrm{GPa} \). Lab Test will be conducted using ANSYS software. (10 Marks) l1g.4
