Which condition(s) listed below is (are) not critical to control residual stresses? [a] Dynamic loading together with compressive hydrostatic pressure. [b] Gears found in an automotive transmission system. [c] Structures which are exposed to temperature ranging from -40 deg C to +40 deg C. [d] Normal stresses acting on the component ranging from -1 GPa to -1.5 GPa. [e] None of the above. Select the manufacturing process(es) that will always generate tensile residual stresses. [a] Quenching of low carbon steel just below the eutectoid temperature. [b] Quenching of eutectoid steel from the austenitic temperature. [c] Quenching of low carbon steel with 5% ferrite and 95% austenite. [d] Quenching of 0.015% of carbon steel from the eutectoid temperature. [e] None of the above. What are the reason(s) to control residual stresses? [a] Improve both the yield and ultimate strength. [b] Prolong the life expectancy of the component under dynamic loading. [c] Improve the fatigue strength of the material. [d] Increase the strain to fracture of the material. [e] None of the above.
