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

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

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 object, learners examine how aeration develops in a hydraulic pump. A brief 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.

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.

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

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

Studies show that more than 75 percent of all hydraulic system failures are a direct result of unclean oil. In this interactive object, learners examine the three primary types of hydraulic system filters. A brief quiz completes the activity.

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

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

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.
