Why are aluminum alloy washers used with steel bolts on aluminum alloy parts in lowtorque applications?
- A.
Reduce shearing
- B.
Prevent vibration
- C.
Prevent corrosion
- D.
Reduce shimming
Correct Answer
C. Prevent corrosionExplanation
Aluminum alloy washers are used with steel bolts on aluminum alloy parts in low-torque applications to prevent corrosion. When two different metals come into contact, such as aluminum and steel, a chemical reaction called galvanic corrosion can occur. This can lead to the deterioration of the metals and weaken the overall structure. By using aluminum alloy washers, it creates a barrier between the aluminum and steel, preventing direct contact and reducing the risk of corrosion.Rate this question:

- B.
By a galvanized-plated steel covering
- C.
The bolt head is marked with a triangle
- D.
The bolt head is marked with the letter S
Correct Answer
D. The bolt head is marked with the letter SExplanation
Special bolts are identified by marking the bolt head with the letter S. This marking helps distinguish special bolts from regular bolts and allows for easy identification during assembly or maintenance processes. The other options mentioned, such as zinc-plated nickel steel covering or galvanized-plated steel covering, are not specific to special bolts and may be used for regular bolts as well. Therefore, the marking of the letter S on the bolt head is the most reliable and consistent method of identifying special bolts.Rate this question:

What part of a cannon plug completes the electrical circuit?
- A.
Metal shells
- B.
Connector halves
- C.
Dielectric contacts
- D.
Pin-and-socket contacts
Correct Answer
D. Pin-and-socket contactsExplanation
Pin-and-socket contacts complete the electrical circuit in a cannon plug. These contacts consist of pins on one connector half and corresponding sockets on the other half. When the plug is inserted, the pins and sockets make contact, allowing the flow of electricity through the circuit. The metal shells provide structural support and protection, while the connector halves hold the pins and sockets in place. The dielectric contacts act as insulators, preventing the pins and sockets from touching each other and causing a short circuit.Rate this question:

- C.
Lowest setting at least four times
- D.
Lowest setting at least six times
Correct Answer
B. Maximum setting at least six timesExplanation
It is important to cycle the torque wrench through the breakaway torque at the maximum setting multiple times before using it. This helps to ensure that the wrench is calibrated correctly and that any initial resistance or sticking is overcome. By doing this at least six times, it provides a more thorough check and reduces the chances of any inaccuracies in the torque readings.Rate this question:

Turbulence affects fluid-flow in a hydraulic line by
- A.
Increasing velocity and viscosity
- B.
Increasing volume and displacement
- C.
Creating resistance and loss of energy
- D.
Creating resistance and energy increase
Correct Answer
C. Creating resistance and loss of energyExplanation
Turbulence in a hydraulic line disrupts the smooth flow of fluid, causing resistance to the movement of the fluid. This resistance leads to a loss of energy as the fluid encounters obstacles and irregularities in the flow path. Therefore, turbulence creates both resistance and a decrease in energy efficiency within the hydraulic system.Rate this question:

How is the piston installed in an accumulator?
- A.
In either direction
- B.
Hollow end towards the air side of the accumulator
- C.
Hollow end toward the fluid side of the accumulator
- D.
Drilled passage toward the air side of the accumulator
Correct Answer
B. Hollow end towards the air side of the accumulatorExplanation
The piston is installed in an accumulator with the hollow end towards the air side of the accumulator. This is because the air side of the accumulator is typically pressurized, and the hollow end of the piston allows for the movement of air and the compression of the gas inside the accumulator. Placing the hollow end towards the fluid side of the accumulator would not allow for proper pressurization and operation of the accumulator. Similarly, a drilled passage towards the air side of the accumulator would not serve the purpose of pressurizing the gas. Therefore, the correct installation is with the hollow end towards the air side.Rate this question:
