Learners examine the drawing symbols used for counterbore, countersink, spotface, radius, diameter, and depth. In the quiz that completes the activity, they associate these symbols with machining applications.
How Current Requires Voltage
By Terry Bartelt
This learning activity uses a water pressure analogy to present the concept that voltage pressure is required to cause current flow.
Rotating Vector Representation of the Sine Function
The learner will be able to represent steady-state AC sinusoidal signals using phase vectors, which will lead to a simplified technique of analyzing AC circuits in a very similar way that we analyze DC circuits.
Voltage and Resistors
By Tim Tewalt
This is an animated troubleshooting exercise that takes voltage measurements to determine the fault of three different series circuits. There are six review questions that enable the learner to determine the effectiveness of the troubleshooting presentation.
Statics - Trig: Law of Sines: Calculations Using a TI-36X Calculator
By Steve Whitmoyer
In this animated object, learners use a TI-36X calculator to determine forces.
The Accounting Definition
By Lynette Teal
Learners examine the accounting process of recording, classifying, summarizing, interpreting, and communicating.
Parallel RL Circuit Practice Problems
By James Bourassa, John Rosz
In this interactive object, students calculate inductive reactance, impedance, current, and power in parallel RL circuits.
Brakes: Measuring Brake Drums
By Ken Kempfer, Dan Claus, John Hadjikyriacos, Kevin Guthrie
Learners examine the proper way to set up standard and metric micrometers to measure the wear on a brake drum.
The Appendicular Skeleton
By Barbara Liang
In this animated object, learners examine the bones of the appendicular skeleton.
Interpreting Engineering Drawings: Common Abbreviations
By Glenn Sokolowski
In this interactive object, learners read the common abbreviations used in engineering drawings and then test their knowledge in three short exercises.
Spheres: Basic Terminology
You'll practice defining terms related to spheres and identifing parts of spheres.
Cutting Speeds and RPM Calculations for Drill Press Operations
You'll practice calculating and selecting the proper cutting speeds for various drill press operations.
Medical Terminology: Abbreviations
You'll become familiar with some common medical abbreviations.
