The steel bar shown in Figure 11-3 (see Example 11-2) is subjected to a compressive load of 648,000 lb in the z direction in addition to the forces shown. Calculate the new dimensions of the bar.

Figure 11-3

Example 11-2

A 12-in.-long 1-in.-by-3-in. ASTM A36 steel bar is loaded as shown in Figure 11-3. The proportional limit is 34,000 psi. Compute (a) the strains in the x and y directions and (b) the total dimensional changes in the x and y directions. Refer to Appendix G for necessary mechanical properties.
