The flow of oil (k=0.145 w/m. k, µ= 0.605 kg/m. s = 0.605 n. s/m2 ) in a journal bearing can be treated as parallel flow between two large isothermal plates with one plate moving and the other stationary. consider two such plates are separated by 0.7 mm thick oil film. the upper plate moves at a constant velocity 8 m/s, while the lower plate is stationary. the temperatures of the upper and lower plates are 40°c and 15°c, respectively. a. obtain relations for the velocity and temperature distributions in the oil. b. determine the maximum temperature and where it occurs, and c. the heat flux from the oil to each plate.

unlike the threaded fasteners which are used to clamp the machine members, power screws are used to transmit power. common applications of power screws are: screw jacks: to lift weight. lead screw of lathe: for axial movement of tool and its precise positioning.

i mean i gues

explanation:

answer:

d. attempt to find the owner, then leave your information if you cannot find them.

explanation:

d. represents both (b) and (c).

more logical as well.

b and c are to complicated.

glad i could , give me a follow, so if you need with any other question, im here.

explanation:  

an electrode is a metal whose surface serves as the location where oxidation-reduction equilibrium is established between the metal and what is in the solution.
