A hydraulic system uses liquid to transmit power. It is designed to create the energy required in the fluid to make the entire system operate.
Learning Objectives
- Understand fluid power
- Define hydraulics
- Describe the differences between hydrostatic and hydrodynamic systems
- List the advantages of a fluid power system
- Identify the basic components of a fluid power system
- Compare a hydraulic and pneumatic system
- Compare four different types of power systems

Hydraulics is based on physics. As a result, it is crucial that you understand the theoretical concepts and fundamental laws applicable to hydraulics. Parameters to control include force, speed, acceleration, path, flow rate, and pressure. In addition, you need to understand the fundamental laws of hydraulics, such as the continuity equation, energy equation, and pressure losses due to friction.
Learning Objectives
- Analyze and discuss the theoretical concepts applicable to hydraulics
- Summarize parameters and their units
- Understand the fundamental laws of hydraulics

Hydraulic fluid plays an important role in a hydraulic system. Without hydraulic fluid, the service life of other components would be much shorter.
Learning Objectives
- Identify the functions of hydraulic fluids
- Understand the different types of hydraulic fluids
- Describe the different classifications of hydraulic oils and flame-retardant liquids
- Know how to select hydraulic oils based on characteristics and purpose
- Understand the importance of periodically checking hydraulic fluids
