Trans-Aerospace Industries has just begun a multimillion-dollar project. It has a team of 15 engineers working on 6 different components of a new jet they would like to launch in 2015. For this project, they have hired 1 lead engineer, 3 supervisors, and 11 certified Pes. Why is
it justifiable to have this large a team with such a management structure?

What precautions should you take to prevent injuries when dealing with heavy loads?

Draw the engineering stress-strain curve for (a) bcc; (b) fcc metals and mark important points.

Acommercial grade cubical freezer, 4 m on a side, has a composite wall consisting of an exterior sheet of 5.0-mm thick plain carbon steel (kst= 60.5 w/m k), an intermediate layer of 100-mm thick polyurethane insulation (kins 0.02 w/m k), and an inner sheet of 5.0- mm thick aluminium alloy (kal polyurethane insulation and both metallic sheets are each characterized by a thermal contact resistance of r 2.5 x 104 m2 k/w. (a) what is the steady-state cooling load that must be maintained by the refrigerator under conditions for which the outer and inner surface temperatures are 25°c and -5°c, respectively? (b) for power saving purpose, which wall material should be increased/reduced in. thickness in order to reduce 50% of the cooling load found in part (a)? redesign the thickness of the proposed material. 177 w/m-k). adhesive interfaces between the q=575.93 w
