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. 25 mm 25 mm r=2.5 mm 25 mm 25 fnm 30 mm r=2.5 mm F
