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.

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

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.

This animated lesson shows several ways that a hydraulic pressure switch, connected in a ladder circuit, causes the cylinder of a hydraulic circuit to perform various applications.

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.

This animated lesson shows how to calculate the amount of force generated by hydraulic cylinders.

Learners observe the four functions of oil in a hydraulic system.

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

In this animated object, learners examine how hydraulic jump affects drain flow and pneumatic pressures in the drain system.
