In this interactive and animated object, learners examine orthographic projection and the Glass Box Theory. Front, side, and top view development is demonstrated with pictorial views of each object to help develop 2D to 3D visualization skills.
Indirect Measurement Instruments
By Kelly Curran
The learner will define indirect measurement, identify common indirect measuring tools, and select the proper measuring tool for the situation.
The Superposition Theorem
By Patrick Hoppe
The superposition theorem is explained as it relates to dc circuit analysis. Examples are given.
Parallel Circuit Analysis Practice Problems: Circuit #5
In this interactive object, learners solve for total resistance and current, the current through each resistor, the voltage across each resistor, and the power dissipated by each resistor.
Series-Parallel DC Circuits Analysis
Learners follow a methodical approach for the dc analysis of series-parallel circuits.
The Dial Caliper
By Barbara Anderegg
Learners review guidelines for the proper use of a dial caliper. Illustrations appear throughout the learning object.
Hydraulic System Pressure
By Terry Bartelt
In this animated activity, learners observe how pressure values throughout a hydraulic system are developed based on pump pressure and the size of the load.
How to Read a Caliper
In this interactive object, learners review how to read a caliper. They then test their skills with eight practice questions.
Series-Parallel Circuit Analysis Practice Problems: Circuit #5
Learners examine a series-parallel circuit and solve 14 problems related to voltage, current, and power. A help screen is provided.
Learners study the fundamental operation of a triac, particularly how it is turned on and off. A brief quiz completes the activity.
Transfer Functions: The RC High Pass Filter
Learners read how the transfer function for a RC high pass filter is developed. The transfer function is used in Excel to graph the Vout. The circuit is also simulated in Electronic WorkBench and the resulting Bode plot is compared to the graph from Excel.
AC Capacitor: A Water Tank Analogy
By Roger Brown
In this animated lesson, students read an analogy comparing water in a "special" water tank to the current "flow" through a capacitor.
Calculating DC Values of a Transistor Amplifier
In this animated activity, learners view the seven steps that are used to calculate voltage and current values throughout a common-emitter transistor amplifier.
In this animated activity, learners examine the three main segments of a hydraulic system: power supply, control, and output. A brief quiz completes the learning object.
Synchronous & Asynchronous Inputs on a JK Flip-Flop
Students examine the operation of synchronous and asynchronous inputs on a JK Flip-Flop.
The Spring-and-Diaphragm Actuator
Learners study an animation of a spring-and diaphragm actuator controlling the opening of a flow valve.
P&ID Tag Numbers
Learners study the types of information letters and numbers placed inside general piping and instrumentation diagram symbols.
What Is Torque?
Learners read a description of torque and study the factors that cause its magnitude to change. A brief quiz completes the activity.
The Edison Wire System
Learners read a description of the wiring configuration of a residential Edison Wire System, which consists of a transformer secondary circuit. The circuit supplies two 115-volt sources and one 230-volt source.
PLC Shift Registers
By Terry Bartelt, Tom Yapp
In this animated activity, learners study how a PLC performs a shift operation. The learning object covers data movement, data entry, PLC wiring, PLC shift register introductions, and programming for a paint can operation.
Basic Elements of Dimensions Used in Engineering Drawings
In this interactive object, students explore the basic elements and common terms associated with dimensions and leaders. A quiz completes the activity.
Current in a Series Circuit
In this learning activity you'll determine what happens to current flow in a series circuit when the resistance is changed.
The Magnetron Ignition System
Learners read an explanation of how the Magnetron Ignition System uses a solid state switching component, a step-up transformer, and magnetism to provide a high voltage spark in a one-cylinder combustion engine.
The schematic symbols of logic gates used in digital circuits are shown.
