By Terry Bartelt, Stephen Schneider
In this animated object, learners examine the causes of air leaks and read how to repair them. The object includes audio.
Learners view an animation showing how the volume of a given quantity of gas varies directly with its temperature.
Direct-Operated, Pressure-Reducing Valves
By Terry Bartelt, Doyle Davis
In this animated activity, learners examine how an adjustable pressure-reducing valve can produce a pressure that is lower at its output than at its input.
Continuous-Cycle Reciprocation Circuit
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.
Slow PLC Scan Time
In this animated object, learners study the problems that develop if the scan time of a PLC is too slow.

The Three-Phase Motor Stator Field
In this animated activity, learners study how stator poles create a rotating field in a three-phase AC motor as a three-phase AC voltage is applied.
On-Off Control of a Feedback System
Learners examine the operation of the on-off control mode using a home heating example. A short quiz completes the activity.
The IR Comp Network
In this animated activity, learners examine the circuitry in a DC variable speed drive that keeps the motor running at a constant speed as the load varies.
In this animated activity, learners examine how the speed of a motor may change if the voltage from the power source fluctuates due to power line irregularities. This lesson has audio content.
Inductive Proximity Sensor Target Considerations
Learners consider the factors that determine how well an inductive proximity sensor can detect an object. Those factors are size, position, and the material from which the target is made. A brief quiz completes the activity.
