It is desired to determine the diameter of a cold drawn steel bar to withstand a tensile preload of 36 kN and fluctuating tensile load varying (0- 72) KN. The bar have geometrical stress concentration factor K. = 2.02 corresponding to a fillet radius of 3.5 mm. Find diameter for infinite life Use: safety factor = 3, S. = 510 Mpa, S .. = 650 Mpa and uncorrected endurance limit = 364 Mpa
