The given framework (see Fig. 2) is loaded vertically by a force F = 5 kN. =The material parameters and dimensions are included E = 210000 MPa, A/= 0.5 m100 mm²,

a) Make a table with the node numbers and coordinates, and a table with the element numbers and the associated node connectivity. b) What are the element stiffness matrices of elements 3, 4, 7 and 8? To do this, first note the general form of the element stiffness matrix for rotated members as a support and then insert thecorresponding values. c) What is the vertical displacement of node vi? d) What stresses and strains do bars 2 and 13 experience?
