Hydraulics
Hydraulics is a branch of science and engineering that deals with the mechanical properties of liquids and their applications in engineering and technology. It focuses on the behavior of fluids, especially water and oil, and how they can be used to generate, control, and transmit power.
Key Concepts in Hydraulics
- Pascal's Law: This law states that when pressure is applied to a fluid in a closed system, the pressure is transmitted equally in all directions.
- Hydraulic Systems: These are systems that use liquid to transmit power. They typically consist of a reservoir, pump, valves, and actuators.
- Hydraulic Machines: These are devices that utilize hydraulic power to perform work, such as hydraulic lifts, jacks, and brakes.
- Hydraulic Fluids: The liquids used in hydraulic systems, such as oil or water, which are chosen based on their specific properties and the requirements of the system.
- Hydraulic Pressure: The force exerted by the fluid on the walls of its container, which determines the amount of work that can be done by the hydraulic system.
Applications of Hydraulics
Hydraulics is used in a wide range of applications, including:
- Heavy machinery and construction equipment
- Automotive systems, such as power steering and braking systems
- Aircraft and aerospace technology
- Marine and offshore systems, including ship steering and loading equipment
- Civil engineering, including the operation of dams and bridges
Study Guide for Hydraulics
To study hydraulics effectively, it is important to understand the basic principles and their practical applications. Here are some key topics to focus on:
- Learn about Pascal's Law and its implications for hydraulic systems.
- Understand the components of a hydraulic system and how they work together to transmit power.
- Explore the different types of hydraulic machines and their functions.
- Study the properties of hydraulic fluids and their selection criteria.
- Examine real-world examples of hydraulic applications in various industries.
- Practice solving problems related to hydraulic pressure, force, and work done by hydraulic systems.
By mastering these concepts, you will develop a solid understanding of hydraulics and its significance in engineering and technology.

Earth/Space Science: Students will use scientific skills and processes to explain the chemical and physical interactions (i.e., natural forces and cycles, transfer of energy) of the environment, Earth, and the universe that occur over time.
Earth History: Explain how sedimentary rock is formed periodically, embedding plant and animal remains and leaving a record of the sequence in which the plants and animals appeared and disappeared.
Explain how sedimentary rock buried deep enough may be reformed by pressure and heat and these reformed rock layers may be forced up again to become land surface and even mountains.
Explain why some fossils found in the top layers of sedimentary rock are older then those found beneath in lower layers: Folding; Breaking; Uplift; Faulting; Tilting.
