A2.U8.SA.L3 Quiz - Hydraulics & Landing Gear

True or False. Pascal’s law states when there is an increase in pressure at any point in a confined fluid, there is a decrease at every other point in the container. (A2.U8.SA.L3)

• True
• False

What does the selector valve do in a hydraulic system? (A2.U8.SA.L3)

• Stores hydraulic fluid for use
• Controls the direction of hydraulic fluid
