The journal bearings at \(A\) and \(B\) exert only \(x\) and \(z\) components of force on the shaft. Determine the shaft's diameter to the nearest millimeter so that it can resist the loadings without exceeding an allowable shear stress of \(\tau_{\text {allow }}=80 \mathrm{MPa}\). Use the maximum shear stress theory of failure.
