In this animated object, learners read about hydrostatic pressure and observe how it is used to measure the level of a material in a container.

Learners study how a hydrocarbon gas sensor operates and why it is used. A short quiz completes the activity.

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 animated activity, learners observe how pressure values throughout a hydraulic system are developed based on pump pressure and the size of the load.

This interactive object is designed to help learners memorize schematic symbols used in hydraulic diagrams. Learners quiz themselves using electronic flashcards.

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

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.

This animated lesson demonstrates hydraulic pressure switch applications when the switch is connected to a ladder circuit to operate in a hydraulic system.

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 to calculate the amount of force generated by hydraulic cylinders.

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

In this screencast, learners examine why the piston of a hydraulic cylinder extends slower than it retracts. A brief quiz completes the activity.
