A steel plug has been interference fit into an aluminum block during the assembly of a diesel engine while at an ambient temperature of 20 °C. Please see dimensions below. The steel has a Young's Modulus of 207 GPa, and the aluminum has a Young's Modulus of 70 Gpa. The aluminum block has a yield strength of 120 MPa. The steel has a thermal expansion coefficient of 11 x 10-6 1/°C, and the aluminum has a thermal expansion coefficient of 22 x 10-6 1/°C. If the engine is stored at the south pole research station at an ambient temperature of -70°C, Find the factor of safety for the aluminum block. 1 30 mm Aluminum block Steel Plug 20.05 mm 20.03 mm 20.09 mm 20.07 mm o Aluminum block Cross-Sectional Schematic Diagram - Not to Scale - Prior to Interference Fit.
