The pedal system shown in the figure is exerted by both an up and down mechanism. These forces are Fmax=350*SN/10 N, Fmin=-150*SN/10 N. It is desired that h/b = 5 seen in the figure. This piece is AISI 1040 and has a maximum tensile stress of 670Mpa and a yield stress of 540Mpa. Known weakening factors are known as kb=ky=kd=0.8. The notch factor for all stresses is assumed to be Kç=1.5. It is desired to last up to its minimum indefinite life at the cross-section measurement point (bxh) shown in the figure. According to Goodman theory, what should be the minimum size (b and h value) of this section in order to meet this condition. SN=89
