engineering recuitment ONGC AEE Mechanical Mock Test 2025 Design of Machine Elements Design Against Fluctuating Load Soderberg Curve
A machine component is subjected to fluctuating stress that varies from 40 to 100 \(\frac{{N}}{{mm^2}}\). The correct endurance limit is 270 \(\frac{{N}}{{mm^2}}\). The ultimate tensile strength and yield strength of the material are 600 and 450 \(\frac{{N}}{{mm^2}}\) respectively. Determine the factor of safety using the Soderberg line.
