The Cycloidal Gear Drive
The learner will gain an understanding of the inner workings of the cycloidal gear drive while watching a video and listening to an explanation of its features.
The Strain Wave Gear Principle
The learner will understand the inner workings of the strain wave gear principle.
The Induction Motor Slip
By Terry Bartelt, Terry Fleischman
In this animated object, learners examine how the rotation of an induction AC motor's armature slips behind the synchronous rotational speed of the stator's field to create magnetic fields. These fields interact and produce torque. A quiz completes the activity.
Cascading Magnitude Comparators
By Terry Bartelt
Learners read an explanation of how to connect two 7485 ICs to compare binary numbers by creating an 8-bit comparator. Diagrams and charts are presented.
By Kelly Curran
In this learning activity you'll review angles and different types of angular measuring tools associated with manufacturing.
Reversing the Rotation of DC Motors
Learners view animations showing how to change the connections to cause a DC motor to reverse its rotation. A short quiz completes the activity.
Safe Handling and Installation of Shielding Gas Cylinders
The learner will understand proper safe handling and installation procedures for shielding gas cylinders.
Logic State Signals

The Open-Collector Logic Device
In this animated object, learners view the operation of an open-collector inverter with and without a pull-up resistor.
Students look at the power dissipated by a single gate and by an IC. The concept of average current draw is introduced and examples are provided.
The Electrician's Wheel of Laws Quiz
By James Bourassa
Learners test their knowledge of the variations of Watt's Law and Ohm's Law with this quiz.
Cutting Tapers using the Taper Attachment
This video will show you how to setup and cut a taper using a taper attachment.
GMAW Modes of Transfer
The learner will identify the advantages and disadvantages of the four modes of GMAW transfer.
Change Model: How to Change
By Barbara Liang
Learners reflect on their own attitudes toward change and list them in the order they might experience them. In a separate exercise, they prioritize the actions a group might take when faced with change in the workplace.
