QUESTION 2 For the spring and bar assemblage shown in the figure, determine the nodal displacements, the forces in each element, the reactions and the stress in the bar. For data, please use the given expressions, where n is the last non-zero digit of your student number. Data: k=nx 275 [N/mm] L = n x 0.3 [m] E = n x 10" [Pa] A = n x 10-3 [m] F = n x 104 [N] TTTTTTT www QUESTION 3 L F Consider the bar shown in the figure, determine the nodal displacements, element stresses and support reactions. Data: E = n x 10" [Pa] L = n x 35 [mm] A = n x 10-4 [m] For data, please use the given expressions, where n is the last non-zero digit of your student number. A = n x 10-3 [m] L = n x 20 [mm] L3 = n x 30 [mm] F = n x 200 [N] L4 = n x 55 [mm] LL L1 L2 L3 L4
