While conducting a secondary wire resistance test, Technician A states that wire resistance
should be approximately 12,000 ohms per
foot. Technician B says that resistance should
be about 50k ohms (50,000 ohms) maximum
for long spark plug cables. Who is right?
(A) A only.
(B) B only.
(C) Both A and B.
(D) Neither A nor B.

Fluids at rest possess no flow energy. a)- true b)- false

Afull journal bearing has a journal diameter of 27 mm, with a unilateral tolerance of -0.028 mm. the bushing bore has a diameter of 27.028 mm and a unilateral tolerance of 0.04 mm. the l/d ratio is 0.5. the load is 1.3 kn and the journal runs at 1200 rev/min. if the average viscosity is 50 mpa-s, find the minimum film thickness, the power loss, and the side flow for the minimum clearance assembly.

Manometers are good examples of measuring instruments, nowadays they are not as common as before. a)-capacitive probe gauges b)-gravitational gauges deformation ) gauges d)-digital gauges
