Estimate the axial infinite fatigue strength (10⁶) and 10³
fatigue strength for a 25 mm diameter reversed axially loaded steel
bar having Su =950 Mpa, Sy = 600 Mpa and is made from a “cold
drawn” steel.
Assume: T< 840º F, 99 % Reliability, CG = .8
For 10^6 cycles fatigue strength is 186.96 MPa
For 10 ^3 cycles fatigue strength is 712.5 MPa
