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 learning activity you'll review the six different ways in which electricity is produced: chemical, friction, heat, light, magnetism, and pressure.

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

Learners examine the formulas for calculating work in ft-lb units and power in ft-lb/min. units.

In this interactive object, learners practice their 3D visualization skills by identifying the correct isometric view of an object. Front, side, and top orthographic views are shown.

Learners examine an animated motion-controlled robotic arm and observe the operation of a PID (Proportional-Integral-Derivative) control that makes movements quickly without overshooting or having a steady-state error. This activity has audio content.

Learners view animations showing how a time-of-flight flowmeter uses ultrasonic sound waves to measure the flow of a liquid.

In this interactive object, learners read an introduction to Class 1, Class 2, and Class 3 levers and then take a quiz.

Learners read how to determine the location of a contour for a specific location given a TIN.

In this learning activity you'll determine what happens to current flow in a series circuit when the resistance is changed.

This interactive object is designed to help learners memorize schematic symbols used in pneumatic diagrams. Learners quiz themselves using electronic flashcards.

Learners follow a methodical approach for the dc analysis of series-parallel circuits.

Learners study the types of information letters and numbers placed inside general piping and instrumentation diagram symbols.

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 and interactive object, learners follow steps to perform the process identification procedure for the Ziegler-Nichols Continuous Cycling Tuning Method. A short quiz completes the activity.

Learners observe how to cascade PLC counters to extend the maximum count of one counter.

In this learning activity you'll build a resistor's color code based on the bands.

Learners study an animation of a spring-and diaphragm actuator controlling the opening of a flow valve.

Learners examine the drawing symbols used for counterbore, countersink, spotface, radius, diameter, and depth. In the quiz that completes the activity, they associate these symbols with machining applications.

In this interactive object, learners analyze a series-parallel DC circuit problem in a series of steps. Immediate feedback is provided.

The superposition theorem is explained as it relates to dc circuit analysis. Examples are given.

Learners perform the steps required for the Ziegler-Nichols Reaction Curve Tuning Method. The process identification procedure is performed, calculations are made, and the proper PID values are programmed into the controller.

In this animated activity, a drill-and-clamp machine is used to show an application of a pressure-reducing valve. Recommendations on how to properly make pressure adjustments are also provided.

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.

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.
