For the plane trusses with inclined supports shown in Figure P3-50, solve for the nodal displacements and element stresses in the bars. Let A = 2 in2 , E = 30 106 psi, and L = 30 in, for each truss. 3 2000 lb Use Matlab Figure P3-50 For the plane trusses with inclined supports shown in Figure P3-50, solve for the nodal displacements and element stresses in the bars.
