The joint is subjected to the force system shown in the figure below \( \quad \) where \( P_{1}=230 \mathrm{lb} \) and \( P_{2}=470 \mathrm{lb} \). The member has a rectangular cross-sectional area of width \( 0.5 \mathrm{in} \). and thickness \( 1 \mathrm{in} \). Figure 1 of 1 Part A Determine the normal stress at point \( A \). Express your answer to three significant figures and include appropriate units. Determine the normal stress at point \( A \). Express your answer to three significant figures and include appropriate units. Part B Determine the normal stress at point \( B \). Express your answer to three significant figures and include appropriate units. Part C Determine the shear stress at point \( A \). Express your answer to three significant figures and include appropriate units. Part D Determine the shear stress at point \( B \). Express your answer to three significant figures and include appropriate units.
