How Does it Work? - Hydraulic Systems

Hannah explores hydraulic systems, learning about Pascal's Law, key components like reservoirs, pumps, valves, and actuators, and how force is transmitted through liquids. She observes a hydraulic digger, understanding the role of hydraulic cylinders and the importance of valves in controlling the system. The video concludes with insights into how hydraulic systems use physics principles to operate machinery efficiently.

What fundamental principle explains the equal transmission of pressure in a liquid within a closed container?

• Newton's Third Law

• Archimedes' Principle

• Pascal's Law

• Bernoulli's Principle

Which component in a hydraulic system is responsible for holding the liquid?

• Pump

• Valve

• Reservoir

• Actuator

In a hydraulic system, what is the role of actuators?

• To hold the liquid

• To move the liquid through the system

• To convert liquid energy into movement

• To control the flow of liquid

What do valves control in a hydraulic system?

• The type of liquid used

• The temperature of the liquid

• The flow and direction of the liquid

• The color of the liquid

How do hydraulic systems use the principles of physics to operate machinery?

• By using magnetic fields

• By using electrical energy

• By using the properties of liquids

• By using the properties of gases
