2. the gearset for a precision enclosed gear drive mates a 20° normal pressure angle helical 16-tooth pinion and 48-tooth gear set, each with a helix angle of 30° a normal diametral pitch of 6 teeth/inch, and face width is 2 in. for both full thickness (k8 = 1) gears. the geometry factors for bending strength are jp = 0.423 and jg = 0.529. the pinion transmits 5 hp at 300 rpm from a uniform source to a uniform load. the gears are grade 1 steel, through-hardened at 200 brinell, made to no. 6 quality standards. they are uncrowned and to be accurately and rigidly center mounted. assume a pinion life of 108 cycles and a reliability of 0.90. determine the agma bending and contact stresses and the corresponding factors of safety.

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?
