GMAW Modes of Transfer
The learner will identify the advantages and disadvantages of the four modes of GMAW transfer.
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.
Visual Logic Basic Programming: Using Flow Charts
By Jason Vosters
In this learning activity you'll understand what flow charts are and how they're used to create computer programs.
Logic State Signals
By Terry Bartelt
In this learning activity you'll identify the voltage levels produced or recognized by digital logic devices as valid or invalid logic state signals.
Cascading Magnitude Comparators
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.
Using Gage Blocks: Discussion and Quiz
By Barbara Anderegg
In this learning activity you'll identify the consequences of using gage blocks incorrectly.
Simplified Sampling Plans for Attributes (Z1.4)
By John Stewart
In this interactive object, learners examine simplified sampling plans and tables based on the ANSI/ASQ Z1.4 standard. An exercise completes the activity.
Wire Feed Welding Gun Assembly
By Dave Hoffman
In this interactive object, learners follow steps to assemble a wire feed welding torch or gun.
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.
The MOD Number
By Patrick Hoppe
Learners read how to calculate the MOD number and how it is used.
In this learning activity you'll explore the history behind gage blocks.
Procedure for Setting the Tool Length Offsets on a Vertical CNC Machining Center with a Fanuc O-M Control
By Les Rhines
Students view how the tool length offsets are set on the CNC Machine. They read a description of a method that uses a 2-inch gage block as a height reference.
Development of a Boolean Expression for a Combinational Logic Circuit
Learners view an animated demonstration of how to determine the final output of the combinational circuit.
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.
In this learning activity you'll review the operation of a NOR gate by using a truth table, a Boolean Algebra equation, a switch analogy, and a written statement.
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.
Gage Block Combinations Review
By Kelly Curran, Janet Braun
In this learning activity you'll test your ability to select the proper gage blocks when making a stack.
