$(20$ points$)$ As an engineer for your company, you have have been asked to procure $10$ of these

shafts for a project that has a very tight budget of $$1350.$ One supplier claims that the shaft will

easily support a bending stress of $30$ ksi and will charge $$\frac{125}{s}$haft. A second supplier claims its

product will only support a max bending stress of $22$ ksi at a cost $$\frac{140}{?}$ shaft. A third company has

the shaft rated at $25$ ksi max bending stress at a cost of $$\frac{115}{s}$haft. However, you have learned that

the company has questionable practices regarding disposal of manufacturing waste. Discuss how

you would handle this procurement in terms of engineering knowledge, budget considerations, and

ethics.
