Repeat Problem 2.3-4, but now include the shortening dAC is not to exceed 4.0 mm? weight of the bar. See Table I-1 in Appendix I for the weight density of steel.

Problem 2.3-4

A vertical bar consists of three prismatic segments A₁, A₂, and A₃ with cross-sectional areas of 6000 mm², 5000 mm², and 4000 mm², respectively. The bar is made of steel with E = 200 GPa. Calculate the displacements at points B, D, and E. Ignore the weight of the bar.
