Figure 1 below shows (1) an unnotched bar and (2) a notched bar of the same minimum cross-section. Both bars are machines from AISI 1050 normalized steel. For each bar, estimate (a) the value of static tensile load P causing a fracture and (b) the value of a fluctuating axial load from 0 to P that would be just on the verge of producing eventual fatigue fracture (in about 1 to 5 million cycles). Reflect on the effect of the notch. r = 2.5 mm 35 mm 30 mm 30 mm 30 mm 30 mm r = 2.5 mm (1) (2) Figure 1
