A steel propane tank for a barbecue grill has a \( 600 \mathrm{~mm} \) inside diameter and a wall thickness of \( 3 \mathrm{~mm} \) The tank is pressurized to \( 490 \mathrm{kPa} \). Determine the normal stress perpendicular to the welding seam. \[ \begin{array}{l} 9.18 \mathrm{MPa} \\ 24.5 \mathrm{MPa} \\ 2.79 \mathrm{MPa} \\ 22.33 \mathrm{MPa} \\ 49 \mathrm{MPa} \end{array} \] Determine the tensile force per \( \mathrm{mm} \) length of the weld between the upper and lower sections of the tank. \[ \begin{array}{l} 276.6 \mathrm{~N} / \mathrm{mm} \\ 73.5 \mathrm{~N} / \mathrm{mm} \\ 262.2 \mathrm{~N} / \mathrm{mm} \\ 125.4 \mathrm{~N} / \mathrm{mm} \\ 219 \mathrm{~N} / \mathrm{mm} \end{array} \] Determine the absolute maximum shear stress in the cylindrical portion of the tank. Answer: MPa
