The assembly shown in (Figure 1) consists of two 2014-T6 aluminum rods \( C D \) and \( E F \) having a diameter of \( d=30 \mathrm{~mm} \), an \( A 992 \) steel rod \( A B \) having a diameter of \( 30 \mathrm{~mm} \), and a rigid member \( G \). The supports at \( A, D \), and \( F \) each have a stiffness of \( k=300 \mathrm{MN} / \mathrm{m} \). Assume \( L=770 \mathrm{~mm} \). Figure 1 of 1 Determine the average normal stress developed in rod \( A B \) when the load is applied. Express your answer to three significant figures and include the appropriate units. Part B Determine the average normal stress developed in rod \( C D \) when the load is applied. Express your answer to three significant figures and include the appropriate units. Determine the average normal stress developed in rod \( E F \) when the load is applied. Express your answer to three significant figures and include the appropriate units.
