O The bars, shown in sketches (a) and (b), are made from cold-drawn, AISI 1050 QT at 425 °C
medium carbon steel. For each of the bars determine
The maximum static tensile load (P) causing fracture,
• The maximum alternating (completely reversing) axial load ±P that would be just on the verge of
producing eventual fatigue failure.
When the load varies from 10 kN to 40 kN. Determine the safety factor for each bar using the
Modified Goodman relationship.

Tensile and fully reversed loading fatigue tests were conducted for a certain steel alloy and revealed the tensile strength and endurance limit to be 1200 and 550 MPa, respectively. If a rod of this material supply were subjected to a static stress of 600 MPa and oscillating stresses whose total range was 700 MPa, would you expect the rod to fail by fatigue processes? Hint: You may want to plot a diagram to aid in presenting your answer.
