Learners examine the differences and similarities between hydraulic and pneumatic systems.
A Timer-On Application
By Terry Bartelt
In this interactive object, learners view a practical application of a PLC Timer-On function.
Sine Wave Fundamentals: Practice Problem #9
By Patrick Hoppe
In this interactive object, learners determine the Vp, Vp-p, Vrms, Vavg, and the frequency of a sine wave that is displayed on an oscilloscope screen.
DC/AC I: Unit 4 Sample Exam
In this interactive object, learners answer nine questions about series and parallel circuits. Immediate feedback is provided.
Learners examine the different types of lines used on a P&ID diagram and the types of connections they represent. They test their knowledge in a matching exercise.
The Multiplication of Force by a Hydraulic System
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.
Pascal's Law and Hydraulics
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.
The Hydraulic System
Examine the components of a hydraulic system.
The Hydraulic Pressure Switch
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.
By Terry Bartelt, Stephen Schneider
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.
