Answer the following questions: a. Write five properties of element stiffness matrix b. Write five properties of structural stiffness matrix c. Write five properties of the global stiffness matrix d. Will subdividing a truss element into many smaller elements improve the accuracy of the solution? Explain e. Explain when element force P is positive or negative. f. For a given spring element, explain why we cannot calculate nodal displacement u and u when nodal forces f and are given. g. Explain what "striking-the-rows" and "striging-the-columns" mean. h. Explain why we need to define the local coordinates x-y in 2D truss element. i. Explain how to determine the angle of a 2D truss element. j. When the connectivity of an element is changed from i →j to j → 1, will the global stiffness matrix be the same or different? Explain why

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?
