For the bar subjected to the linearly varying axial line load shown in Figure P10–7, use the linear strain (three-noded element) with two elements in the model, to determine the nodal displacements and nodal stresses. Compare your answer with that in Figure 3–31 and Eqs. (3.11.6) and (3.11.7). Let A = 2 in.2 and E = 30 106 psi. Hint: Use Eq. (10.5.22) for the element sti¤ness matrix.
