5. Figure below shows that the members of the truss have a cross-section area of 2.3 in² and Young's modulus E-10 psi. When FEA approach is used to determine the deflection of each joint (numbered in red color 1, 2, 3), then the local stiffness matrix of element 2 (numbered in black color 2) in the figure will be Y 0.25 0.433 -0.25 -0.433 Ľx 0.433 -X A) 0.75 -0.433 -0.75 -0.25 -0.433 0.25 0.433 k 200 lb 2 -0.433 -0.75 0.433 0.75 0.25 -0.433 -0.25 0.433 -0.433 0.75 0.433 -0.75 -0.25 0.433 0.25 -0.433 0.433 -0.75 -0.433 0.75 0.25 -0.433 -0.25 0.433) -0.433 -0.75 0.433 -0.75 k -0.25 0.433 -0.25 0.433 0.433 -0.75 0.433 0.75 C) 1 -0.25 0.433 -0.25 0.433 0.433 0.75 0.433 -0.75 -0.25 0.433 -0.25 -0.433 k 0.433 -0.75 -0.433 0.75 60° 2 B) D)
