Normally Open vs. Normally Closed Pressure Control Valves
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 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.
This interactive object is designed to help learners memorize schematic symbols used in hydraulic diagrams. Learners quiz themselves using electronic flashcards.
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.
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 colorful and animated activity, learners study the operation of a needle valve and the operation of the needle valve with a check valve. A brief quiz completes the activity.
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 animated lesson shows how a ladder circuit causes the cylinder of a hydraulic circuit to continuously extend and retract after a Start button has been pressed.
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 view the following physics concepts in action: force, friction, horsepower, work, power, inefficiency, resistance, inertia, and energy.
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.
