If True Airspeed is 470 knots, what is the Equivalent Air speed?
- 662 knots
- 550 knots
- 278 knots
Is there a formula for this?
Which of the graphs shown is given by the equation; y = 2x^3 + 4x + 3?
- a
- b
- c
Please write your question here.
During a Rockwell Hardness test, what dimension is measured?
- The diameter of the indent.
- The depth of the indent.
- The diameter and depth of the indent.
isn't what we should see in the microscope is the diameter of the indent and then calculate the area, then knowing the depth?
If the speeder spring pressure of a CSU is increased the blade will
- coarsen off.
- fine off.
- will not move.
Isn't speeder spring pressure increased by the flyweights moving out? Therefore this is overspeed condition - blades coarsen?
To prevent wet arc tracking
- cable grips should be kept tight.
- ensure hot stamp printing is controlled.
- cables should not be excessively stretched.
Why is it?
An abradable lining in the fan case
- prevents fan blade tip rub.
- produces less leakage at tips for anti-ice.
- provides acoustic medium.
how can it reduce noise?
-40 degrees C in Fahrenheit is
- -72 degrees F.
- -8 degrees F.
- -40 degrees F.
How?
What is the atomic number of the element shown here? (It is not hydrogen, just fictional element)
- 7.
- 3.
- 4.
i know that atomic number Z is up on the left
What work is done if a force of 100 N moves a body 15 metres?
- 150 kJ.
- 1.5 kJ.
- 0.15 J.
Please how?
Fahrenheit may be converted to Celsius by using the equation
- degrees C = 5/9 * ( degrees F - 32).
- degrees C = 5/9 * ( degrees F + 32).
- degrees C = 9/5 * ( degrees F - 32).
How? F=9/5×C+32 and C=1/9×(F-32)
The function of a propeller pitch lock is to prevent the propeller from
- coarsening.
- reducing below flight fine pitch.
- fining off in the event of pitch lock mechanism failure.
So the PITCH LOCK stops the propeller from fining off when the PITCH LOCK fails, does that make any sense at all?
A 0.5 in. diameter pipe is to be joined using standard nuts and fittings. What coupling would you use?
- AN8-8852-1.
- AN8-8852-2.
- AN8-8852-8.
Does the -8 mean diameter in 16th's?
A drive shaft has a speed 150pi radians a second. What is the speed in RPM?
- 4500.
- 9000.
- 1500.
Can somebody explain this please?
The Sine wave signals of a circular time base are
- in phase.
- phase separated by 90degrees.
- phase separated by 180degrees.
guys explain kindly
When drilling out a rivet, use a drill
- larger than the rivet hole.
- same size as the hole.
- smaller than the rivet hole.
thought it was smaller than hole when drilling out the rivet??
When comparing the average values of an AC generator output, to the peak values
- average voltage = 0.707 * peak voltage.
- average voltage = 0.63 * peak voltage.
- average voltage = same as the peak voltage.
explain
What is the value of a monolithic capacitor with 103 on it?
- 1000pf.
- 10,000pf.
- 100,000pf.
10^3 =1000pf correct me if am wrong

- 6000 RPM.
- 12000 RPM.
- 3000 RPM.
Please Explain
The speed of an AC motor can be affected by the
- field current.
- armature current.
- pairs of poles.
how

- 10V
- 6V
- 30V
explain
An AC inductive circuit has an inductance of 10 mH and a frequency input of 1000Hz. The opposition to current flow is approximately
- 63 ohms.
- 63,000 ohms.
- 630 ohms.
KINDLY someone explain to me
In a series circuit with 3 resistors, the current is
- lower than the smallest.
- the total of all 3 using ohms law to find the current.
- even in all 3.
