A steel component is subjected to alternate cyclical loading. The steel follows Basquin's law for high cycle fatigue, o, x N7 = C1 (where the stress amplitude is in MPa). Ignore the geometric detail and assume that Marin's modifying factors are all equal to 1. You are given the minimum stress omin = -213 MPa, the maximum stress omax = 213 MPa. The material data are Tensile strength ơUTS = 539 MPa, Basquin's constant c, = 875 MPa, Basquin's exponent a = 0.085. a) Calculate the stress ratio R, the stress amplitude o, in MPa and the mean stress am in MPa. The answers are acceptable with a tolerance of 0.01 for R and of 1 MPa the stresses. R : MPa MPa alculate th ding lifo Cucloc (toloran
