Ramsay Mechanical Test Questions


Hydraulics and Pneumatics

Which type of valve should be used when a precise, low flow is required?

A. Check
B. Needle
C. Gate
D. Both A and B
Correct Answer
Incorrect Answer

The correct answer is B.

A needle valve is constructed as an elongated, narrow plunger inside a small port. This structure enables the valve to regulate the flow with high precision. However, it is not capable of withstanding high pressure.

A check valve is a valve that enables flow in only one direction, using a ball, a piston, or a spring-loaded flapper.

A gate valve operates by lifting a gate from the path of the fluid. These gates are planar and are mostly used with high-volume, unrestricted flow.

What is D in the above drawing?

Ramsay print reading mechanical sample question
A. 74.5
B. 73.5
C. 75.3
D. None of the Above
Correct Answer
Incorrect Answer

The correct answer is A - 74.5

Ramsay mechanical test print reading answer

There are two ways to find D in the figure as shown.

'v' value is unknown but we know that it is half of 'u'. Therefore:



D=65+9.5 or 84-9.5=74.5


Power Transmission

What is the aim of flexible couplings?

A. Reduce load from the motor
B. Allow shaft misalignment
C. Installation at various machinery parts
D. Amplify torque
Correct Answer
Incorrect Answer

The correct answer is B.

The aim of flexible couplings (such as universal joints or Oldham couplings) is to allow a certain degree of misalignment between connected shafts (it may be an axial, lateral, or angular misalignment). Rigid couplings, on the other hand, require absolute alignment between shafts and are somewhat limited in that manner.


Preventive Maintenance

If dirt is not removed from the motor windings, it may cause:

A. Blockage of the ventilation process
B. Voltage and current imbalance
C. Single phasing
D. None of the Above
Correct Answer
Incorrect Answer

The correct answer is A.

The dirt on the motor windings causes blockage of the air ventilation in the windings and therefore is the correct choice.

Voltage and current imbalance can be caused by loose connections.

Single phasing is an electrical supply-related consequence.


Tools, Materials, and Equipment

What is the value shown on the micrometer?

Ramsay tools and materials sample question
A. 2.72 mm
B. 2.97 mm
C. 2.92 mm
D. 2.79 mm
Correct Answer
Incorrect Answer

The correct answer is A - 2.72 mm.

2.5 + 0.22 = 2.72 mm

This reading is tricky. we are not sure if we see a whole mark on the barrel. in order to know whether we should count it or not we look at the thimble and see if the value is at the beginning of a new round OR at the end of the last round. in this case, the thimble shows a value of 22 which is very close to completing the round (back to zero). thus, it means we should not count the mark that we related to on the barrel. Therefore, the last mark on the barrel shows the value of 2.5mm and we should add 0.22 mm to it.

Remember: when the barrel shows the slight beginning of a new mark, you should check whether to count it or not based on the value that the thimble displays.



Coolant leakage into the engine cylinders is most likely to occur because of defective:

A. Manifold gasket
B. Cylinder head gasket
C. Water pump
D. Shaft seal
Correct Answer
Incorrect Answer

The correct answer is B.

A cylinder head gasket is a seal that is fitted between the piston cylinder head and the engine block, installed in internal combustion engines. A defective gasket will cause leakage of fluids such as coolant or engine oil into the cylinders. In such cases, efficiency is reduced and combustion is compromised.

AC/DC Theory

In a 110V electrical system, there are three appliances: appliance A (550W) appliance B (770W), and appliance C (330W). Given that all appliances operate simultaneously, what is the minimum required fuse rating?

A. 30A
B. 25A
C. 20A
D. 15A
Correct Answer
Incorrect Answer

The correct answer is C.

The minimal fuse rating should be higher than the normal operating current of the system. Since an electrical system is connected in parallel, the total current in the system when all three appliances are working is the sum of all three.

The current consumption of each appliance is calculated by:

I = P/V


  • I = Current [Ampere]
  • P = Power [Watt]
  • V = Voltage [Volt]


  • Appliance A consumes 550/110 = 5A
  • Appliance B consumes 770/110 = 7A
  • Appliance C consumes 330/110 = 3A

The total current in the system is 5 + 7 + 3 = 15A

In order to withstand normal working conditions, the minimal fuse amperage rating must be greater than 15A, thus 20A.


Control Circuits

Identify the relay type shown below:

amazon ramsay maintenance test electrical theory sample question
D. None of the Above 
Correct Answer
Incorrect Answer

The correct answer is B.

SPDT is a single pole double throw relay. The schematic diagram of an SPDT is shown below.

There are three terminals:

  • COM (common)
  • NO (normally open)
  • NC (normally closed).

When the relay is OFF, the COM terminal is connected with the NC terminal and when the relay is ON, the COM terminal is connected with the NO terminal. The schematic diagram of SPST (single pole single throw) and DPDT (double pole double throw) are also shown below.

Electronics and PLC

What is the equivalent Boolean expression for the PLC program below?

amazon control systems plc sample question
Correct Answer
Incorrect Answer

The correct answer is A.

Below are the steps of analysis:



In induction motors, the difference between the synchronous and asynchronous speed of the rotor is referred to as:

A. Single phasing
B. Slip
C. No-load speed
D. None of the above
Correct Answer
Incorrect Answer

The correct answer is B.

Induction motors which are also called asynchronous motors work on the principle of induction which is inducing a current in the rotor by changing the magnetic field of the stator.

We can differentiate two definitions of speed in induction motors:

  • Synchronous speed – The speed of the changing magnetic field.
  • Asynchronous speed – The speed of the rotor (which is different from the synchronous speed).

The difference between these two is called slip. Therefore, B is the correct choice.

As for the other answers, single phasing (A) occurs when one of the motor terminals is loose or disconnected making the motor run on a single-phase. No-load speed of a motor (C) is the maximum speed of a motor when there is no load applied.


Test Instruments

In electrical circuits, voltmeter is always connected in ____________ and ammeter is always connected in ____________.

A. series, parallel
B. series, series
C. parallel, parallel
D. parallel, series
Correct Answer
Incorrect Answer

The correct answer is D.

In electrical circuits, voltmeters are always used in parallel to the nodes where the potential is required to be determined. However, ammeters are always connected in series to measure the desired current in the branches. These connections are shown in the figure below.
