The steel shaft is made from two segments: \( A C \) has a Part A diameter of \( 0.5 \) in., and \( C B \) has a diameter of \( 1 \mathrm{in} \). The shaft is fixed at its ends \( A \) and \( B \) and subjected to a Determine the maximum shear stress in the shaft torque of \( 500 \mathrm{lb} \cdot \mathrm{ft} . G_{\mathrm{st}}=10.8\left(10^{3}\right) \mathrm{ksi} \). (Figure 1) Express your answer to three significant figures and include the appropriate units.
