An aluminum bar having a cross- sectional area of 0.5 in2 carries the axial loads applied at the positions shown in the figure shown. Compute the total change in length of the bar and the strain of the aluminum bar. Consider E = 10 x 106 psi. Assume the bar is suitably braced to prevent lateral buckling. Solve the problem above if the points of application of the 6000- lb and the 4000-lb forces are interchanged. 7000 b 6000 lb 3 ft 5 ft 5000 b 4ft 4000 b
