Learners view two animations that show the effects of eddy currents.

In this animated and interactive object, learners calculate the area and centroid of a semicircle.

In this animated object, students view a depiction of how force is transmitted by hydraulic cylinders and confined fluid.

In this animated and interactive object, learners study how a DC circuit, consisting of a diac, a capacitor, and two resistors, causes a light-emitting diode to turn on and off. A brief quiz completes the activity.

Students read a step-by-step approach on how to connect a voltmeter to a circuit when making a measurement.

Students examine the procedure to measure current with an analog ammeter. The use of Function and Range switches is explored along with reading the needle position on the meter scale. 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 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 test their knowledge of 14 geometric tolerance control symbols.

You'll practice defining terms related to spheres and identifing parts of spheres.
