In this highly interactive object, learners associate basic line types and terms with engineering drawing geometry. A quiz completes the activity.
Parallel LC Circuit Tic-Tac-Toe 1
By Terry Bartelt
By playing a game of tic-tac-toe, a student can review what happens to currents and voltages throughout a parallel LC circuit when the applied frequency increases from 0 Hz toward resonance.
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.
The Dial Caliper
By Barbara Anderegg
Learners review guidelines for the proper use of a dial caliper. Illustrations appear throughout the learning object.
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.
Voltmeter Circuit Connections
Students read a step-by-step approach on how to connect a voltmeter to a circuit when making a measurement.
Analog Ammeter Operation
Students examine the procedure to measure current with an analog ammeter. The use of Function and Range switches is explored along with reading the needle position on the meter scale. A brief quiz completes the activity.
Basic Symbols Used in Engineering Drawings
By Kelly Curran, Glenn Sokolowski
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.
Basic Types of Dimensioning Used in Engineering Drawings
Learners examine the basic types of dimensioning including unidirectional and aligned systems, and linear, aligned, angled, arrowless, chain, datum, chart, tabular, radius, diameter, typical, and reference dimensions.
GD&T: Geometric Characteristic Symbols
By Glenn Sokolowski
In this interactive object, learners test their knowledge of 14 geometric tolerance control symbols.
