Pressure-Reducing Valve Application
By Terry Bartelt, Stephen Schneider
In this animated activity, a drill-and-clamp machine is used to show an application of a pressure-reducing valve. Recommendations on how to properly make pressure adjustments are also provided.
P&ID Tag Numbers
Learners study the types of information letters and numbers placed inside general piping and instrumentation diagram symbols.
Pneumatic Schematic Symbol Flashcards
This interactive object is designed to help learners memorize schematic symbols used in pneumatic diagrams. Learners quiz themselves using electronic flashcards.
Simple Pneumatic Circuits
Learners examine the operation of five pneumatic animated circuits that use directional control valves, pilot lines, check valves, needle valves, and cylinders.
Learners observe how to cascade PLC counters to extend the maximum count of one counter.
Three-Phase Delta Transformer Calculations
Using a memory shortcut for calculations, the learner determines line and phase values of current in a three-phase AC configuration. Practice problems complete the activity.
Manufacturing PPE Mini-Sim
By Excelsior College
This activity is a simulation that allows the learner to practice personal protective equipment tasks.
Reaction Curve Tuning Example
Learners perform the steps required for the Ziegler-Nichols Reaction Curve Tuning Method. The process identification procedure is performed, calculations are made, and the proper PID values are programmed into the controller.
The Three-Phase AC Generator
By Terry Fleischman
In this 3D animated object, learners examine the way in which a three-phase generator produces three sine waves with three armature coils. A quiz completes the activity.
Designing a Ladder Diagram
In this animated object, learners examine the design of a ladder circuit that provides manual control to a water pumping system. Students also study modifications to the circuit as the complexity of the system increases.
Calculating Horsepower, RPM, and Torque
In this animated and interactive object, learners examine the formula for horsepower and work practice problems.
Hydraulic Schematic Symbol Flashcards

This interactive object is designed to help learners memorize schematic symbols used in hydraulic diagrams. Learners quiz themselves using electronic flashcards.
Comparing Hydraulics and Pneumatics
Learners examine the differences and similarities between hydraulic and pneumatic systems.
Armature Action of AC Motors
In this animated object, learners study the rotation of the magnetic stator field of an AC motor and how it interacts with the armature to cause rotation. A short quiz completes the activity.
The Force of a Hydraulic Cylinder
In this interactive object, learners read how to determine the force created by a hydraulic cylinder during extension and retraction. A brief quiz completes the activity.
Fundamentals of a DC Motor
Learners study the interaction between the conductors of the stator and the armature inside a DC motor, which causes the shaft to rotate. A short quiz completes the activity.
In this animated activity, learners study how the magnetic field of an armature can distort the DC motor's main magnetic field. A brief quiz completes the object.
Motor Starter Protection
Learners examine the ways in which a motor starter circuit is protected by a main circuit breaker and overload heaters when there is excessive current.
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.
