technician b says that negative air pressure draws more overspray through spraybooth filters than positive air pressure.

Burgers vector is generally parallel to the dislocation line. a)-true b)-false

An ideal otto cycle with air as the working fluid has a compression ratio of 8. the minimum and maximum temperatures in the cycle are 300 k and 1340 k. use constant specific heats at room temperature to determine (a) the amount of heat transferred to the air during the heat- addition kj/kg, (b) the thermal efficiency, and (c) the thermal efficiency of a carnot cycle ope limits. process, in rating between the same temperature

Inspection for bearing condition will include: (clo4) a)-color b)-smell c)-size d)-none of the above
