- A compound bar consisting of bronze, aluminum, and steel segments is loaded axially as shown in the figure. The cross-sectional area of the bronze, aluminum, and steel are 412 mm2, 601 mm2 , and 260 mm2 respectively.Determine the change in length (in mm) of the bar if P = 30280 N.The moduli of elasticity are 81.17 GPa for bronze ,71.07 GPafor aluminum , and 202.36 GPa for steel . Round off the final answer to four decimal places.Consider a 1 m-long bar of 2024-T81 aluminum alloy with a 20mm-diameter and the following property data: E=70GPa Y.S.=410MPa T.S.=480MPa %Elongation at failure=8% What will be the length of the bar under a structural load of 1.2×10^5N in tension? Your answer should be in units of meters (m).The radius and length of a steel cylinder are 60 mm and 120 mm, respectively.
