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

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.

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

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 activity, learners examine the three main segments of a hydraulic system: power supply, control, and output. A brief quiz completes the learning object.

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

The operation of a hydraulic brake valve, including the internal components, is presented using animations.

In this screencast, 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 colorful and animated activity, learners examine the four functions provided by a hydraulic reservoir. A brief quiz completes the learning object.

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.

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.

In this animated activity, learners examine how cavitation occurs in a hydraulic pump. A video clip is included. Learners then test their knowledge in a brief quiz.

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.

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

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.

In this animated object, learners examine the operation of a hydraulic relief valve and its internal components. A brief quiz completes the activity.

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.

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

In this interactive object, learners examine how work is performed in foot-pounds by a hydraulic system that uses a pump and cylinder. 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.
