A rod with a cross-sectional area of A and loaded in tension with an axial force of P = 9800 N undergoes a stress of σ = P/A. The material strength of the rod is 165 MPa. Take a design factor of 3 and calculate the minimum value of the diameter of the solid circular rod in millimeter based on the strength condition. Using the table shown, select the preferred diameter closest in excess to the calculated diameter. Millimeters 1.4, 1.5, 1.6, 1.8, 2.0, 2.2, 2.5, 2.8, 3.0, 3.5, 4.0, 4.5, 5.0, 5.5, 6.0, 6.5, 7.0, 8.0, 9.0, 10, 11, 12, 14, 16, 18, 20, 22, 25, 28, 30, 32, 35, 40, 45, 50, 60, 80, 100, 120, 140, 160, 180, 200, 250, 300 Determine the safety factor of the rod. Note: To express the answer of the safety factor, use 2 figures after the decimal point.
