The complete stress-strain diagram for a particular stainless steel alloy is shown in Figure Q-7 Q-7a. This diagram has been enlarged in Figure Q-7b to show in more detail the linear portion of the stress-strain diagram. A rod made from this material is initially 800 mm long at a temperature of 20°C. After a tension force is applied to the rod and the temperature is increased by 200°C, the length of the rod is 804 mm. Determine the stress in the rod, and state whether the elongation in the rod is elastic or inelastic. Assume the coefficient of thermal expansion for this material is 18 x 10-6/ °C.

Due to an applied static loading, the principal stresses at a point of a machine component are σ1 = -150 MPa and σ2 = 60 MPa. If the design of the component is to be done using a LESS conservative failure theory, then yielding will just begin if the designer chooses a ductile material with the yield strength, Sy=___. If the factor of safety needs to be at least 4 by using a MORE conservative theory, what is the minimum yield strength needed for the material?
