Students read information about basic logic gates including the gates' names, symbols, Boolean expressions, pronunciations, and truth tables. They then complete a matching exercise.
Learners examine the different types of lines used on a P&ID diagram and the types of connections they represent. They test their knowledge in a matching exercise.
In this screencast, Geometric Dimensioning & Tolerancing: The Feature Control Frame, learners examine geometric characteristic symbols, tolerances, datum feature symbols, and other control frame information.
In this learning activity you'll review the operation and schematic symbols of various types of switches and push buttons used for electronic circuits.
This interactive object is designed to help learners memorize the schematic symbols used in ladder logic diagrams. Learners quiz themselves using electronic flashcards.
Learners read definitions of atomic symbols, atomic numbers, and mass numbers and then answer questions about the number of neutrons, protons, and electrons in select elements.
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.
