The company flew an aircraft to mobile alabama for maintenance, repair, and overhaul (mro) service. the aircraft basic weight was 2886 and had a moment calculated at 101673.78. while in the hanger the aircraft was required to be modified. two 15 pound seats located at station +71 were required to be removed. a new cabinet weighing 97 pounds was installed in place of the seats (at station +71). also at station +71, an upgraded seat weighing 20 pounds was installed. as part of the new modification, new radio equipment was installed at station +94 weighing 30 pounds. calculate the new weight of the aircraft and cg of the aircraft after modification:

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
