Learners examine the differences and similarities between hydraulic and pneumatic systems.
The RC Time Constant
By Patrick Hoppe
Learners examine the concept of the RC time constant. The instantaneous voltage across the capacitor is calculated.
Strength of Materials: The Centroid of a Triangle
By Steve Whitmoyer
In this animated and interactive object, learners calculate the area and centroid of a triangle.
Conductive Probe Sensors
By Terry Bartelt
In this animated object, learners study how conductive probe sensors are used to measure conductive liquid in a container.
In this animated object, learners examine the fundamental operation of a diac including how it is turned on and turned off. A brief quiz completes the activity.
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.
In this animated object, learners examine how aeration develops in a hydraulic pump. A brief quiz completes the activity.
The Hydraulic Color Code
Learners read an explanation of the color code used on schematic diagrams for hydraulic circuits. Circuit examples for each color are shown.
Pneumatic Air Conservation
In this animated activity, learners read about air loss in a pneumatic system and ways to reduce the leakage. The object includes audio.
