A compound bar consisting of bronze, aluminum, and steel segments is loaded axially as shown in the figure. The cross- sectional area of the bronze, aluminum, and steel are 427 mm?, 634 mm2 , and 272 mm? respectively.Determine the change in length (in mm) of the bar if P = 30924 N.The moduli of elasticity are 81.06 GPa for bronze ,73.13 GPafor aluminum, and 200.97 GPa for steel. Round off the final answer to four decimal places.

Hi can you please help me at this point with C and D here?

Good morning interns, This is Ms. Gorman from the sales department. We have just secured a new, multi-million-dollar account! We are so good here in the sales department of Heavy-Duty Box Inc. The manufacturing director, Mr. Tsosie, has instructed me to send this problem out to all of you as this will be a deciding factor in which of you get offered the full-time positions available at the end of the internship! Our new client, Beastie Bearings Inc., needs the heaviest duty box we make here at Heavy-Duty Box for their bearings. The following email from Ms. Venegas from Beastie Bearings provides the information you will need. Remember, our mark-up sales price is 150% of what it costs us to manufacture the product. The cheaper it is for us to produce the box, the lower the cost for our client. There is also a grading rubric attached that Mr. Tsosie will be utilizing in evaluating your work. I would advise you to follow it well if you want a position!   Good luck interns,   Ms. Frances…
