Fly By Wire systems in the fully active mode, the actuators will
- both be active.
- one be standby.
- both be damped.
is this correct?shouldnt it be one in active mode, the other in damping mode?
What is the reflected impedance in the primary of the transformer circuit shown?
- 20 ohms
- 500 ohms
- 50 ohms
? should be 50 ohms !
Armature reaction in a DC generator causes
- MNA to move in the opposite direction of rotation.
- MNA to move in the direction of rotation.
- GNA to move in the direction of rotation.
Another question says MNA rotates opposite armature rotation, which is true then? thx for your help.
Operating thrust reversers at low ground speeds can sometimes cause
- sand or other foreign object ingestion, hot gas re-ingestion.
- hot gas re-ingestion, compressor stalls.
- sand or other foreign object ingestion, hot gas re-ingestion, compressor stalls.
Hi to everybody. Could u tell me why the compressor stalls in this case? thank
For the CGS system, the force is
- the 'Newton' which produces an acceleration of 1cm/s2 for a mass of gram.
- the 'dyne' which produces an acceleration of 1cm/s2 for a mass of gram.
- the 'pd1' which produces an acceleration of 1 cm/s2 for a mass of gram.
I havent seen anything like this in any of the notes I have anyone understand it.?
In the anodic film inspection and sealing test, if a good seal has been accomplished
- the dye mark will not rub off.
- the dye mark has no importance.
- the dye mark will rub off.
help please. i'm confused.
In a an DC motor, the rotation of the MNA
- is opposite to the rotation of the armature.
- is slightly less speed than the rotation of the armature.
- is the same as the rotation of the armature.
MNA rotates in the same direction than the armature, right?
Which of the following would be used to calculate transformer turns ratio?
- Secondary turns / primary turns.
- Primary turns * secondary turns.
- Primary turns / secondary turns.
isn't this wrong?
The colour code on sheet metal indicates
- only the specification of the material.
- the spec and gauge of the material.
- that the material is from an approved source.
any link plz
When examining a piece of metal through a magnifying glass, hair line cracks would indicate
- crevice corrosion.
- intergrannular corrosion.
- surface corrosion.
r u sure about the answer or could it be :surface corrosion'
A mass of 10kg placed 2 metres away from a pivot will have a moment of
- 196 NM.
- 150 NM.
- 980 NM.
Is this correct I thought it would have been 20nm
If the aircraft is slipping in turn
- the bank angle is too great.
- the bank angle is too small.
- the nose of the aircraft is positioned too low.
plz explain.i'm not sure if the answer is for skid or slip
The vertical fin of a single engined aircraft is
- parallel with both the longitudinal axis and vertical axis.
- parallel with the longitudinal axis but not the vertical axis.
- parallel with the vertical axis but not the longitudinal axis.
isn't the fin for single engine aircraft is parallel to virtical axis and offset to the left of the longitudinal axia,
15.4 / 2 - 2 (4.6 - 15.7) =
- -14.5
- 26.5
- 29.9
Please explain.
What is the main purpose of a frise aileron?
- Increase drag on the up going aileron.
- Decrease drag on the up going wing surface.
- Help the pilot overcome aerodynamic hinge loads.
frise aileron produces more drag on up going wing or is it to the up going aileron.little confused..
During a climb from a dive
- the thrust required is greater than required for level flight.
- the thrust required is lower than for level flight.
- the thrust required is the same as for level flight.
plz explain
The tension in the cable of a crane is 2500 N and it lifts a load through 50m, what is the work done on the load?
- 1.25 * 10^5 J
- 2.50 * 10^4 J
- 5.00 * 10^3 J
Please explain.
Which of the following NDT methods requires that the surface of the test piece is cleaned down to bare metal?
- Eddy Current.
- Magnetic Particle.
- Dye-penetrant.
Why is this not eddy current?
During a turn, the stalling angle
- increases with bank angle.
- decreases noticeably.
- remains the same.
plz explan
Which wing increases drag when the ailerons are moved?
- Both wings increase drag but the wing with the up-going aileron has more.
- Both wings experience an equal increase in drag.
- Both wings increase drag but the wing with the down-going aileron increases more.
plz explan
An experienced engineer fits the wrong seal during a routine component change. This is
- task based.
- rule based.
- time based.
what is the right answer and why?
Gas pressure through the turbine section will generally
- increase.
- remain the same.
- decrease.
y is it decrease?
In a 4:1 step up transformer, what would give a reflected impedance of 1 kOhm?
- 1 kOhm.
- 16 kOhm.
- 4 kOhm.
why??
Potentiometers are used as a
- variable voltage source.
- variable resistor.
- variable current source.
Potentiometers are used as voltage dividers are the not? they have 3 connections, surely a rheostat would be a better variable resistor?
Diodes connected in parallel would act like an
- an NAND gate.
- an AND gate.
- an OR gate.
Why is the answer AND gate? For example,you put 2 diodes parallel to each other. If the current flow through one of the diodes,wouldnt the circuit is still complete?
