Solve Example 3.2 again using ten linear elements instead of five. Determine the displacement at the free end of the tapered bar and compare your answer with the result obtained in the example.
Example 3.2
Consider the tapered bar shown in Fig. 3.3 with E = 210 GPa and P = 18 kN. The cross-sectional areas of the bar at the left and right ends are 0.002 m2 and 0.012 m2, respectively. Use linear bar elements to determine the displacement at the free end of the bar.
