Learners view examples of devices that prevent mistakes from occurring.

Learners view a demonstration showing that line-neutral voltages and line-line voltages are not in-phase with each other, but have a definite 30-degree relationship.

Learners examine an animated motion-controlled robotic arm and observe the operation of a PID (Proportional-Integral-Derivative) control that makes movements quickly without overshooting or having a steady-state error. This activity has audio content.

In this animated object, learners examine the proper way to reset a counter instruction in a programmable controller.

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 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.

Learners read an explanation of the color code used on schematic diagrams for hydraulic circuits. Circuit examples for each color are shown.

In this animated activity, learners read about air loss in a pneumatic system and ways to reduce the leakage. The object includes audio.
