For the plane trusses supported by the spring at node 1, determine the nodal displacements and the stresses in each element. Assume E=300(GPa), A=10x10*(m) for both truss members. 0 sm 5 m SO KN 50 kn po 10m Sk = 2000 kN/m a. By hand calculation. You may use MATLAB for inverse or solving system of equation. b. By MATLAB code. Upload your codes to Blackboard. (aeng_3100_s20_hw3_91b.m) For the plane trusses supported by the spring at node 1, determine the nodal displacements and the stresses in each element.
