How can you work this out without a calculator?
A ram has a piston with 2 in2. Another ram with a piston of 4 in2 will provide
- triple the force.
- double the force.
- square the force.
Hi, I could do with some help on this question. I have not see this method of specifying a ram and piston combination. What is the difference between a "2 in2" and a "4 in2" piston, are the designations relating to piston and rod diameter? Thanks, Graeme.
A cylinder filled with water to half a metre will exert a pressure of
- 49.0 Pa.
- 4900 Pa.
- 9800 Pa.
Hi, can someone please explain?
A spring, operating within its elastic range, shortens by 60mm when a load of 480N is applied to it. Calculate the total shortening when the load is increased by 120N
- 82mm.
- 45mm.
- 75mm.
Hi, can someone give me the formula to calculate this?
(x + y)^2 / (x + y)^8 has a base and exponent of
- (x + y)^10.
- (x + y)^-6.
- (x + y)^1/4
is this is nt worng question?
The type of fluid in an oleo strut will depend upon
- the type of seal material.
- heat generated in operation of the system.
- type of fluid most readily available.
i thought the answer to this question was type of seal material, does anyone know why its heat generated in operation as the type of fluid may break the seal down.
When light rays enter a medium with a different refractive index they
- split in two.
- stay aligned.
- change speed.
Will it not change direction too?
On a high winged aircraft in a banked turn, which of the following are true?
- The down-going wing loses lift producing a stabilizing effect.
- The up-going wing loses lift causing a stabilizing effect.
- The wing dihedral alone causes a stabilizing effect.
Please explain this.
At which frequency is the calibration of frequently used crimping tools carried out?
- Bi-annually (every two years)
- Annually (once per year)
- Every 1000 crimps
How do I know when 1000 crimps were made?
The right answer should be every x time?
The stalling speed of an helicopter blade
- does not change.
- is increased when the helicopter is heavier.
- is increased when the helicopter is lighter.
Blade stall is more likely when the HC is heavier. Does that not mean that the stalling speed of the blade is increased when the HC is lighter and will stall at a lower speed when the HC is heavier? Just getting ready for my A3 and this is confusing me!
An 8 data input multiplexer has how many Data Select lines?
- 8.
- 3.
- 2.
Can anyone explain how?
In a diode clamper, if the resistor is removed making the time constant equal to C x r where r is the reverse resistance of the diode, this will ensure a
- long time constant.
- short time constant.
- variable time constant.
i dont understand this question can anyone plzz explain it ?
Consumption of alcohol
- increases mental and physical reaction times.
- does not change mental or physical reactions.
- decreases mental and physical reaction times.
Help with this one?
The landing speed of an aircraft is 54 m/s. If the maximum deceleration is 3m/s2 the minimum length of runway required is
- 162m.
- 486m.
- 360m.
solve pls
An inductor of resistance 5 kO and inductance 2mH is connected to a DC circuit. The time constant is

- 40 ms.
can anyone please explain? thanks
The name given to this shape.
- Trapezoid
- Parallelogram
- Rhombus
this shape looks like rhombus
If the resistance of a resistor which is in series with two other resistors is doubled
- the current in that resistance is doubled.
- the volts drop across that resistor increases.
- the current in that resistance is halved.
why cant it be current halved?
Given that s=0, solve the equation s=ut + 1/2at^2 for the two possible values of t.
- t=0, t=2u/a.
- t=0, t=a/2u.
- t=0, t=-2u/a.
Hi, can some please explain?

If the bypass ratio is 0.7:1, the 0.7 pounds of air is
- fed into H.P compressor compared to 1 pound fed around it.
- fed around the engine to 1 pound fed into H.P. compressor.
- bypassed for every 1 pound at the intake.
anybody please explain

i don't understed this quastion. could someone help me?
The output from a rotating armature AC generator would be taken from
- either the rotor or the stator.
- the rotor.
- the stator.
i cant understand the difference between output and output windings,
some questions mention output is from rotor and others output windings from stator.Am confused!!
The specific gravity readings of a lead-acid cell taken twice after charging shows substantially lower value.
- Cell is defective
- You top up the cell with distilled water
- You replace the cell
is this question tricky or this question is acting devil, why can't "replacing the cell" be a right answer. but i consider both answer to be correct. if any one can lighten up then that would be wonderful.
A radar antenna is facing left. On ground test, if you move the vertical gyro to simulate a right bank, the antenna
- will move up
- will move down
- will not move
Help please! can any body picture this?
