Sketch the free-body diagram of element 1 of the frame analysed in Problem 12.15 highlighting all actions applied to it.

Problem 12.15

Using the stiffness method, calculate the nodal displacements and reactions for the frame illustrated below. Assume I = 240 × 106 mm4, A = 6 × 103 mm2 and E = 200 GPa.
