= 9. How many blocks of Fig. 9.1d loading can be applied to a small, smooth uniaxial rod of RQC-100 steel if the given axis has a scale of 200 units 100 MPa, according to the S-N approach? Repeat the calculations if a notch of K, 1.5 and a notch root radius equal to 5 mm had existed, where K, and nominal stress history are based on the net cross-sectional area. =
