. A rectangular steel bar is subjected to a fluctuating load from 30 kN tension to 30 kN compression. The bar is 30 mm wide and 7 mm thick with a hole in the middle that is 4 mm in diameter. Find the fatigue and yield factor of safety if the steel is cold-drawn AISI 1040. If the fatigue factor nf<1 and ny>1 then that means that the system will fail at a finite number of cycles. If that is the case, estimate the number of cycles to failure.

Q3: When a mild steel rod was tested under tension, it was observed that a load of 8 kN causes an extension of 0.024 cm in the rod. The maximum load carried by the steel rod was observed to be 20 kN and the load beyond which stress is not proportional to strain was noted as 10 kN. When the specimen breaks, the elongation in the rod measured was 5.25 cm and the diameter at the fracture observed was 0.455...
