Based on the loads defined for this three dimensional (3-D) truss structure, complete the following for the redesign of outer truss sections: a) Determine the structural loads in truss members AD, AE, BE, CD, CE, and DE. b) Assuming that the truss members will all be constructed of 4130 alloy steel tubing, propose a cross-sectional geometry for each truss member that provides the following safety factors (FoS) - FoS of at least 3 against yielding, and - FoS of at least 1.5 against buckling. The cross-sectional geometry must be of standard stock sizes readily available from suppliers, such as OnlineMetals. c) Calculate the actual FoS for outer truss sections under the maximum defined loads based on your geometry selection(s). d) Estimate the material cost per truss sub-section, which contains the six truss members. e) Discuss the manufacturability of redesigned outer truss sections based on your geometry selection(s).

Air is to be cooled in the evaporator section of a refrigerator by passing it over a bank of 0.8-cm-outer-diameter and 0.4-m-long tubes inside which the refrigerant is evaporating at -20°c. air approaches the tube bank in the normal direction at 0°c and 1 atm with a mean velocity of 4 m/s. the tubes are arranged in-line with longitudinal and transverse pitches of sl- st 1.5 cm. there are 30 rows in the flow direction with 15 tubes in each row. determine (a) the refrigeration capacity of this system and (b) pressure drop across the tube bank. evaluate the air properties at an assumed mean temperature of -5°c and 1 atm. is this a good assumption?
