Aux 2 Unit 3 Quiz 4

Correct Answer:
B) Faster and more forceful response to load changes

Explanation:
Hydraulic actuators can respond quickly and apply significant force almost instantly, which is essential for vessel stabilizers that need to react to changing sea conditions.

Correct Answer:
B) It stores energy in the form of pressurized fluid to smooth out pressure fluctuations

Explanation:
An accumulator helps maintain a steady pressure by storing and releasing pressurized fluid as needed, ensuring smooth operation of the stabilizer even during changes in load or demand.

Correct Answer:
B) To prevent backflow and ensure unidirectional flow

Explanation:
A check valve ensures that fluid flows in only one direction, preventing backflow that could disrupt the operation and safety of the system.

Correct Answer:
A) Pressure relief valve

Explanation:
A pressure relief valve is used to ensure that the pressure in the hydraulic system does not exceed a safe limit, protecting the system components and maintaining consistent operation.

Correct Answer:
B) Directional control valve

Explanation:
A directional control valve manages the flow path of hydraulic fluid, directing it to the stabilizer to control its movement and adjust its position.

Correct Answer:
B) Ability to withstand exposure to water without significant electrical hazards

Explanation:
Hydraulic systems are generally more resilient to water exposure compared to electrical systems, reducing the risk of electrical shorts and failures in wet or marine environments.

Correct Answer:
B) They offer greater force and power density, ideal for heavy-duty marine applications

Explanation:
Hydraulic actuators provide higher power density and can generate more force relative to their size compared to electrical actuators, making them suitable for demanding applications such as vessel stabilizers that require rapid and strong movement.
