Comparing Hydraulics and Pneumatics
By Terry Bartelt
Learners examine the differences and similarities between hydraulic and pneumatic systems.
Hydraulic Systems
In this animated activity, learners examine the three main segments of a hydraulic system: power supply, control, and output. A brief quiz completes the learning object.
Hydraulic System Pressure
In this animated activity, learners observe how pressure values throughout a hydraulic system are developed based on pump pressure and the size of the load.
Hydraulic Directional Control Valves
In this animated activity, learners examine the operation of hydraulic directional control valves and the internal components that divert the fluid.
Pascal's Law and Hydraulics
Using the principle of Pascal's Law, the learner will interpret the gauge readings in a hydraulic system to determine when the system is operating properly under various load conditions and when there is a defect.
The Multiplication of Force by a Hydraulic System
In this animated and interactive object, learners examine a depiction of how force is multiplied by a larger cylinder when pressure from a pump is applied to a smaller cylinder. A short quiz completes the activity.
Determining Hydraulic Cylinder Size
Students read how to calculate the size of a hydraulic cylinder that is required for a particular application. Mathematical formulas are provided.
The Force of a Hydraulic Cylinder
In this interactive object, learners read how to determine the force created by a hydraulic cylinder during extension and retraction. A brief quiz completes the activity.
Designing a Cylinder Dwell Circuit

Boyle's Law (Screencast)
Learners apply the principles associated with Boyle’s Law.
Simple Pneumatic Circuits
Learners examine the operation of five pneumatic animated circuits that use directional control valves, pilot lines, check valves, needle valves, and cylinders.
Hydraulic Schematic Symbol Flashcards
By John Rosz
This interactive object is designed to help learners memorize schematic symbols used in hydraulic diagrams. Learners quiz themselves using electronic flashcards.

Counterbalance Valves
Learners view an animation of a counterbalance valve in operation and examine the valve’s internal structure.
Pneumatic Directional Control Valves (Screencast)
In this animated object, learners examine the operation of two-way, three-way, and four-way directional control valves used in pneumatic systems.
Pilot-Operated, Pressure-Reducing Valve Malfunctions
In this animated activity, users examine the causes of malfunctions in a hydraulic pressure-reducing valve and the problems that result. A short quiz completes the learning object.
The Hydraulic System
Examine the components of a hydraulic system.
The Hydraulic Color Code (Screencast)
In this screencast, learners read an explanation of the color code used on schematic diagrams for hydraulic circuits. Circuit examples for each color are shown.
Charles's Law
Learners view an animation showing how the volume of a given quantity of gas varies directly with its temperature.
Pressure Relief Valves
In this animated object, learners examine the operation of a hydraulic relief valve and its internal components. A brief quiz completes the activity.
Pneumatic Power Supply
In this animated object, learners examine the parts of a pneumatic power system, including the prime mover, compressor, and receiver tank, and how they function.
Single-Cycle Reciprocation Circuit
In this animated lesson, the learner examines how a ladder circuit causes the cylinder of a hydraulic circuit to make a single extension and retraction.
