In this learning activity you'll identify the voltage levels produced or recognized by digital logic devices as valid or invalid logic state signals.
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.
Using a Sine Bar
By Janet Braun
The learner will use the deceptively simple sine bar to measure angles to minutes or even half minutes.
Welding Wire Spool Installation Instructions
The learner will identify the steps and proper techniques for installing a wire spool on a welding machine.
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.
Using Fire Extinguishers
By Terry Bartelt, Pat Jensen
By the end of this learning activity, you’ll know how to understand, use, and maintain different types of fire extinguishers.
Test your skills at reading a ruler.
The Logic Gates
Students read information about basic logic gates including the gates' names, symbols, Boolean expressions, pronunciations, and truth tables. They then complete a matching exercise.
Hydraulic Shear - Part Identification
By Dave Hoffman
The student is shown and then identifies the parts of a hydraulic shear.
General Machine Safety Considerations
By Kelly Curran
This text document lists 27 safety items to consider in a machine shop.
Pedestal Grinder Procedures
This lesson gives the student an overview of grinding wheels and pedestal grinder procedures.
Sizing a Tank Type Water Heater
By Randy Lorge
In this interactive learning object, the learner practices sizing a tank-type water heater for one- and two-family residences, townhouses, and apartments with individual water heaters.
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.
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.
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.
Variation in Manufacturing: The Stable Process
Learners read a brief introduction to in-control and out-of-control conditions and view a series of distribution curves. This is a follow-up to the learning object titled "Quality Basics: Variation."
Units of Measurement
By Barbara Anderegg
In this learning activity you'll explore units of measurement.
Types of Motion Instructions
The learner will identify the types of motion instructions used for programming a robot.
Communicating in the Workplace
By Jennifer Heinritz
Compare the behaviors and situations that interfere with effective communication in the workplace with those that enhance listening skills and career performance.
The Strain Wave Gear Principle
The learner will understand the inner workings of the strain wave gear principle.
What Type of Team Do You Belong To?
Are you a member of a fragmented, conflicted, or smooth- functioning team? Learn the characteristics of each to build a stronger team.
Understanding and Writing Pseudocode: The Basics
In this activity you'll explore how flowchart programs can be converted into pseudocode programming.
In this learning activity, we’ll explore the impact of electric shock on the human body.
In this animated object, learners examine three different types of multivibrators: astable, monostable, and bistable. A brief quiz completes the activity.
