Learners examine the differences and similarities between hydraulic and pneumatic systems.
Excel: Complex Addition
By Patrick Hoppe
Students view the steps to follow to add complex numbers in Excel.
Pressure Measurement Scales
By Terry Bartelt
Learners compare the three scales used in pressure measurements: gage, absolute, and vacuum. A brief quiz completes the activity.
Testing an On/Off Switch
In this learning activity you'll review methods for testing an on/off switch with an ohmmeter and a voltmeter.
Types of Motion Instructions
The learner will identify the types of motion instructions used for programming a robot.
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.
