In this animated activity, learners read about the types of lines found on blueprints. A quiz completes the activity.

Learners examine the operation of five pneumatic animated circuits that use directional control valves, pilot lines, check valves, needle valves, and cylinders.

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.

In this animated object, learners examine the operation of a multiplexer and the function of the data input and selector lines. A brief quiz completes the activity.

In this highly interactive object, learners associate basic line types and terms with engineering drawing geometry. A quiz completes the activity.

Learners compare electromagnetic quantities with the voltage, current, and resistance quantities of an electrical circuit. A brief quiz completes the object.

Learners examine how an electromagnet is formed. Animated illustrations show current running through a coil wrapped around an iron core.

Learners examine the basic types of dimensioning including unidirectional and aligned systems, and linear, aligned, angled, arrowless, chain, datum, chart, tabular, radius, diameter, typical, and reference dimensions.

In this interactive object, students explore the basic elements and common terms associated with dimensions and leaders. A quiz completes the activity.

In this animated object, students examine the steps for wiring an electrical circuit from reading a schematic diagram.

Learners take a close look at the Edison Wire System and observe how the current values through the two lines and the neutral of the system change as the loads vary.

An interactive html page that allows the user to manipulate a Cardioid-like shape generated by lines.

In this animated object, learners examine the operation of a pneumatic directional control valve using air pilot lines.

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.

In this animated object, learners examine the operation of a demultiplexer along with the data output and select lines. A brief quiz completes the activity.

Datum precedence is a fundamental principle in the design and manufacture of mechanical parts and assemblies.

It refers to the order of importance assigned to different datums, which are specific points, lines, or planes on a part, which are used as references for measurement and geometric tolerances.

In this animated activity, learners examine how a voltage is induced into a conductor when the conductor cuts across magnetic flux lines. They also view the four factors that determine how much voltage is generated. A brief quiz completes the learning object.

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.
