The machine component from problem 2 (bar with hole and notches) undergoes variable loading from 42,500N to 45,000N. The part is made from 6061-T6 aluminum (S_u = 310 MPa and S_y = 275 MPa). The machined part requires a reliability of 95%. The large size results in a gradient strength factor of c_G=0.8 (see note c in Table 8.1). Calculate the safety factor. If the safety factor is less than one (i.e., shaft fails), find the number of cycles to failure.

[Proof of Concept] Considéra machined steel circular shaft subjected to maximum and minimum bending moment of 1000 and 4000 lb .in, respectively; and a maximum and minimum torque of 250 and 1600 Ib.in, respectively. Consider the factor of safety to be 2, the yield strength of the materials 40 ksi, and its ultimate strength to be 70ksi.Determine the minimum diameter of the shaft for the case where D is 20% larger than d, the fillet radius is 10% of d, and reliability is 99%.

Write a computer code that can take Tm, Ta, Mm, Ma, choice of material, safety factor, and other necessary assumptions from the user and return an estimated diameter for the shaft.Choice of inputs is up to you. Note that many of the required quantities are themselves function of the shaft diameter. Your code should be submitted with a report.
