Consider the truss shown below: a) Develop the global structural stiffness matrix [K] considering that the axial stiffness of both truss members is identical, i.e. (AE/L)₁ = (AE/L)2= 100 kip/in. b) Report the matrix equation you would use to solve for the displacements at the unconstrained degrees of freedom. c) Report the matrix equation you would use to solve for the unknown reactions. Note that all members are axial members and deflections are small. You do not need to solve the matrix equations for displacements or reactions. 2 4 3 75 kip ↑ 2 30 kip 1 1 6 L. S
