Play an AI-generated podcast conversation about this lesson

What is the main purpose of a hydraulic accumulator?

To store the energy of a gas as kinetic energy

To store the energy of a liquid as pressure energy (correct)

To prevent energy transfer within a hydraulic system

To convert pressure energy into kinetic energy

When does a hydraulic accumulator supply energy to a machine like a hydraulic lift?

When the machine is moving upward

When the machine is moving downward

When the machine is stationary

When the machine needs a large amount of energy (correct)

What happens to the water under pressure if it is not required by the machine connected to the hydraulic accumulator?

It moves the ram upward

It is converted into kinetic energy

It is stored in the cylinder (correct)

It is released into the environment
