For the one-dimensional problem shown in figure Q2 calculate the global problem stiffness matrix before the application of boundary conditions. You may assume that the individual element stiffness are given by K₁ = 10,000 N/m, K₂=5,000 N/m, Ka = 10,000 N/m and that the applied force, F = 500 N. 114 Figure Q2: A One-dimensional Problem [5 Marks] Q 2(b) Again considering the one-dimensional problem shown in figure Q2, calculate the reduced global stiffness matrix after the application of boundary conditions. Q2(c) [10 Marks] Now calculate the displacement of all nodes in the finite element model and explicitly state the global nodal displacement vector. Q 2(d) [5 Marks] Use the element strain displacement matrix [B] to determine the strains in each element in the finite element model. Assume that each element has a length of 5m.
