Q4. A steel cantilever beam is of circular cross-section is subjected to a transverse load at its free end which varies from 45 N up to 135 N down. The strength properties are as follows: Ultimate strength 600 MPa, Yield strength 360 MPa, Endurance limit = 300 MPa. The theoretical stress for 45 N 324 mm concentration factor bending is 1.5 and the notch sensitivity 0.8, at the change of cross-section. Take size factor = 0.8 and surface finish factor = 0.9. Determine the required factor of safety for infinite life using Soderberg's formula as basis for design. (n = 3) 2d d= 12 mm 0.2d 466 mm 135 N Q4.
