In this animated activity, learners view the following physics concepts in action: force, friction, horsepower, work, power, inefficiency, resistance, inertia, and energy.

Learners examine the differences and similarities between hydraulic and pneumatic systems.

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.

In this animated activity, learners examine the operation of normally open and normally closed valves used in hydraulics. A brief quiz completes the learning object.

In this animated object, learners examine how various types of positive and non-positive displacement hydraulic pumps work.

Learners view an animation of a counterbalance valve in operation and examine the valve’s internal structure.

In this animated object, learners examine how aeration develops in a hydraulic pump. A brief quiz completes the activity.

This interactive learning object is designed to help learners memorize the color code used on some hydraulic schematic diagrams. Learners quiz themselves using electronic flashcards.

In this animated activity, learners examine how an adjustable pressure-reducing valve can produce a pressure that is lower at its output than at its input.

Learners examine how fluid enters the inlet of a hydraulic pump because of atmospheric pressure and how pressure is created at the pump’s outlet. This object includes audio.

Learners follow an animated test procedure to determine if the parts of a hydraulic pump are worn.

This animated lesson an exercise that enables students to design a ladder logic circuit using a drag-drop function to cause the cylinder of a hydraulic circuit to extend and retract.

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.

In this interactive object, learners examine how hydraulic oil is contaminated, the types of damage contamination can cause, and the methods used to clean the oil.

This animated lesson shows how a ladder circuit uses timer-on delays to cause an extrusion machine to operate.

In this animated object, learners examine the internal structure of an unloading valve. This learning object includes a video clip demonstrating the use of an unloading valve in a metal stamping application.

In this animated activity, learners examine the operation of hydraulic directional control valves and the internal components that divert the fluid.

Learners view an animation of a sequence valve in operation and examine the valve’s internal structure.

Learners read about the similarities of electronic and hydraulic components and then match the schematic symbols in a drag-and-drop exercise.

Learners read an explanation of the color code used on schematic diagrams for hydraulic circuits. Circuit examples for each color are shown.
