The magnetism that remains after the magnetizing force has been removed is known as
-
Residual magnetism
-
Permeability
-
Molecular magnetism
-
Electromagnetism
Correct Answer
A. Residual magnetismExplanation
Residual magnetism refers to the magnetism that remains in a material even after the magnetizing force has been removed. This phenomenon occurs because some of the magnetic domains within the material become aligned during the magnetization process and retain their alignment. This residual magnetism can be observed in materials like iron or steel, where the domains remain aligned and create a magnetic field. This property is utilized in applications such as magnetic storage devices and electromagnets.Rate this question:

If you must push a wrench rather than pull it, how should you do it?
-
Use the base of your palm and hold your hand open
-
Grip the wrench tightly with both hands
-
Grasp the handle near the socket
-
Grip the wrench tightly near the center
Correct Answer
A. Use the base of your palm and hold your hand openExplanation
To push a wrench, it is recommended to use the base of your palm and hold your hand open. This technique allows for better control and stability while exerting force on the wrench. By using the base of the palm, the pressure is distributed more evenly, reducing the strain on the fingers and joints. Holding the hand open also provides a better grip and prevents the wrench from slipping.Rate this question:

After shutdown a motor continues turning; this is known as
-
Inertia
-
Impedance
-
Inductance
Correct Answer
A. InertiaExplanation
After shutdown, a motor continues turning due to its inertia. Inertia is the property of an object to resist changes in its motion. In the case of a motor, the rotating parts have momentum and will keep rotating even after the power is cut off. This is because the motor's inertia keeps it in motion until an external force stops it completely.Rate this question:

The best step in preventing abnormal amounts of carbon, moisture, and sludge build-up in a diesel engine, is to
-
Perform a preoperational check
-
Operate the unit at idle speed for long periods of time
-
Drain moisture from fuel system periodically
-
Avoid operating the engine for extended periods at no-load
Correct Answer
A. Avoid operating the engine for extended periods at no-loadExplanation
Operating the engine for extended periods at no-load can lead to abnormal amounts of carbon, moisture, and sludge build-up in a diesel engine. This is because when the engine is running without any load, it does not reach its optimal operating temperature, which can result in incomplete combustion and the formation of carbon deposits. Additionally, operating at no-load does not generate enough heat to evaporate moisture in the engine, leading to moisture build-up. Therefore, avoiding operating the engine for extended periods at no-load is the best step in preventing these issues.Rate this question:

The stator windings of a synchronous motor are wound
-
20 degrees apart
-
30 degrees apart
-
90 degrees apart
-
120 degrees apart
Correct Answer
A. 120 degrees apartExplanation
The stator windings of a synchronous motor are wound 120 degrees apart. This is because a synchronous motor operates on the principle of magnetic fields interacting with each other. By winding the stator windings 120 degrees apart, the resulting magnetic fields generated by each winding will also be 120 degrees apart. This phase difference between the magnetic fields is necessary for the motor to operate synchronously with the rotating magnetic field produced by the rotor.Rate this question:

Correct Answer
A. Starting DeviceExplanation
The three-phase induction motor does not require a starting device because it is a self-starting motor. It operates by the principle of electromagnetic induction, where the rotating magnetic field generated by the stator induces currents in the rotor, causing it to rotate. This self-starting capability eliminates the need for an external starting device, such as a starter motor or capacitor, which are typically required in other types of motors to initiate rotation. Therefore, the correct answer is Starting Device.Rate this question:
