For the bar subjected to the linearly varying axial line load shown in Figure P10–7, use the linear.
For the bar subjected to the rectilinearly varying axial line load shown in Figure P10–7, use the rectirectilinear clarify (three-noded atom) delay two atoms in the pattern, to mention the nodal displacements and nodal stresses. Compare your counterpart delay 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 atom sti¤ness matrix.
