1.The cylindrical bearing journal of an overhung crankshaft has been sized for wear and found to require a diameter of 38 mm based on wear analysis. A force analysis of the journal has shown there to be a transverse shear force of 45 kN, torsional moment of 1000 N-m, and bending moment of 900 N-m at the critical cross section of the cylindrical journal bearing. If the fatigue-based stress governs, and has been found to be 270 MPa, calculate whether the 38-mm diameter journal is safely designed to withstand the fatigue loading.
