In this animated object, learners examine three data compare instructions used by programmable logic controllers (PLCs). A practical application to show how these instructions are used in an industrial setting is provided.
How Adding Parallel Branches Increases Total Current
In this animated object, learners follow an analogy of water flowing through pipes and valves to see how current increases in a parallel circuit as branches are added.
In this interactive learning activity, learners explore factors that contribute to the aging process. Learners calculate their age based on biological, psychological, and social experiences. Further reflection allows the learner to consider options and assess issues that impact the aging process.
The learner reads about the kinds of questions that are most effective to use on student questionnaires evaluating instruction. Generic evaluations are less helpful than evaluations focused on the specific types of instruction and learning expected in a content area. Sample questions are provided.
In manufacturing, controlling the production process is critical. Part of this control is knowing when to make adjustments and when to let the line run. Step onto the production line in our manufacturing plant and learn what process variation is and how it impacts your bottom line.
Procedure for Setting the Tool Length Offsets on a Vertical CNC Machining Center with a Fanuc O-M Control
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.
The learner reads an explanation of how to determine lengths for tubing and pipe bending and then performs calculations in an interactive exercise. Two methods for determining angle bends are shown. A calculator is required.
The Operation of a Multiplexer/Demultiplexer Circuit
In this animated object, learners examine how a multiplexer and a demultiplexer work together when their data select lines are connected to the same binary counter.
The Multiplexer/Demultiplexer IC Data Transfer Circuit
In this animated activity, the learner examines how a 74150 IC multiplexer and a 74154 IC demultiplexer work together when their data select lines are connected to the same input devices.
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."
