standard and has been opened read-only to prevent modification. Find text or tools ( PART 2 (a) Your company is thinking of replacing a pair of cast iron gears with grade 2 through hardened steel gears. The life of the pinion is 10^9 cycles. Assuming all operating conditions stay the same, determine the most cost-effective ($/cu. ft.) option between the iron and steel gears based on AGMA contact stress analysis only. Performance between the two options should be the same. (40 points) The hardness of the cast iron gears is HB=225, Sc= (350*HB) psi The cost of cast iron is ($0.075+ $0.0015*HB) per lb. The density of cast iron is 430 lbs./cu. ft. The cost of the Steel is ($0.01 + $0.001*HB) per lb. The density of steel is 460 lbs./cu. ft.

The first photo was the screenshot of my question here in Bartleby. But in other site (chegg), I saw the same problem but the answers are different. On another site also, the answers are the same as of chegg—however, "member AB" was stated, and not BA. I am hoping for clarification on what process to use, and why. Thank you

Write the analysis that assumes that the cross-section is constant andhas an axis of symmetry?

where are the steps for the solution?????
