A Dial Test Indicator may be used for
- checking a round bar for bow.
- checking dimensions to within 0.125 inch.
- checking any known depth measurement.
D.T.I why isnt the 3d option?Because it says "any"?
A shunt is used with
- an ammeter.
- a voltmeter.
- an ohmmeter.
please explain
What is the minimum bend radius of a loom adequately supported at a terminal block?
- 10 * diameter
- 8 * diameter
- 3 * diameter
why is 3*d and not 8*d?
What non-destructive testing method requires little or no part preparation, is used to detect surface or near-surface defects in most metals, and may also be used to separate metals or alloys and their heat-treat conditions?
- Eddy current inspection.
- Magnetic particle inspection.
- Ultrasonic pulse inspection.
isnt eddy current inspecction method only for internal cracks?Why does it mention here that it is used to detect"surface and nearsurface"?
When tapping blind holes
- a set of three taps is used.
- a set of two taps is used.
- a single bottoming tap is used.
what does 3 taps mean?
Springs are manufactured from
- high carbon alloy steel with high strength requirements.
- low carbon alloy steel with high strength requirements.
- high carbon alloy steel with low strength requirements.
i think in module 6 it literally said that the correct answer was "high carbon alloy steel with low strength requirements" am i wrong?Or did i get confused?
Which contains the least amount of heat energy?
- Both 1 kg of ice at 0 degrees C and 1 kg of water at 0 degrees C have the same amount of heat energy.
- 1 kg of water at 0 degrees C has less total heat energy than 1 kg of ice at the same temperature.
- 1 kg of ice at 0 degrees C has less total heat energy than 1 kg of water at the same temperature.
Enthalpy (i.e. heat) of water = Enthalpy of ice + latent heat.
I think the answer should be that ice contain least amount of heat energy. Because ice will need to get additional heat energy to change the state/phase of the substance (ice to water).
If the outer cover of a flexible hose is found to be cracked.
- It is unserviceable due to possible flow restriction.
- It may still be serviceable.
- It is unserviceable since it may leak.
shouldnt it be unservicable?
A secondary earth is
- not less than 0.5mm.
- 18 AWG.
- 22 AWG.
i dont understand
Following a major defect the C of A
- is not affected, however may run out on a time basis.
- will be invalidated and requires a full renewal survey before flight.
- Nothing will happen and the C of A remains fully valid.
i dont undersrand the question help please.
A Transformer with 115V primary voltage and a ratio of 5:1 is supplying a landing light (load 24V 45 amps) is used, what is the current drawn?
- 205 amps.
- 5 amps.
- 9 amps.
why please
The line voltage of a 3 phase star connected AC generator is
- equal to the phase voltage.
- greater than the phase voltage.
- less than the phase voltage.
it is less i think the answer is wrong.
In a parallel LCR circuit, if the capacitance is increased by 4 times, what happens to the impedance of the capacitor?
- Increases by 4 times.
- Remains the same.
- Decreases by 75%.
why is this happening?
A 4:1 step down transformer draws 115 V and 1 A. The output power will be
- 460 V at 0.25 A.
- 28.5 V at 16 A.
- 28.5 V at 4 A.
why?
Three capacitors connected in series, each having a value of 12 picofarads, calculate the total capacitance
- 36 picofarads.
- 4 picofarads.
- 12 picofarads.
i think it is 36
The secondary winding of a transformer has an impedance of 10 ohms and 1500 turns. For the primary winding to have an impedance of 1 kilohm, how many turns must it have?
- 15,000.
- 1,500,000.
- 150,000
why
In a series LCR circuit at resonance, R = 100 ohms, L and C are each 10 ohms. The total impedance is
- zero ohms.
- 100 ohms.
- 30 ohms.
why?
If the phase voltage of a star wound generator is 115V, what would be the line to line voltage?
- 220V.
- 180V.
- 200V.
why?
For the diagram shown find the voltage at point B.
- 7V
- 10V
- 26V
why?
111.1 MHz is
- a VOR frequency.
- a HF frequency.
- an ILS frequency.
IT has even hundreds... S-o why îs not a VOR freq?
120 out of 125 bolts produced are of an acceptable tolerance. What percentage of the bolts are not acceptable?
- 4%
- 5%
- 25%
Why?
What is the equation of the graph shown?
- y = -2.
- x = -2.
- y = 2x.
It shouldn't be y=2?
For an equation 2y = 5x + 3 what is the gradient?
- 3/5x
- 5/2
- 5x+3/2
I dont understand what does gradient mean.Also why is the result 5/2 i think is 5x+3/2
One of the square roots of a positive number is positive. What is the other one?
- positive
- negative
- positive or negative.
why?I dont understand.
A sphere with a radius of 2 cm has a surface area of
- 8pi cm^2.
- 16pi cm^2.
- 64pi cm^2.
Why
