A structural member in a nuclear reactor is made of a zirconium alloy. An axial Part A load of \( 20 \mathrm{kN} \) is to be supported by the member. Use a factor of safety of \( 3.5 \) relative to yielding. \( E_{z r}=100 \mathrm{GPa}, \sigma_{Y}=400 \mathrm{MPa} \). The material has elastic Determine its required cross-sectional area. behavior. Express your answer to three significant figures and include the appropriate units. - Part B What is the load on the member if it is \( 1 \mathrm{~m} \) long and its elongation is \( 0.4 \mathrm{~mm} \) ? Express your answer to three significant figures and include the appropriate units.
