The learner views animation showing how a DC motor is wired and its operational characteristics. A short quiz completes the activity.

Learners review the three formulas for power and work 12 problems. In each of the problems, students are given two of the three variables (voltage, resistance, or current) and asked to solve for power. Immediate feedback is provided.

Students study the concept that the voltage drop across a series circuit resistor is proportional to its resistance. They then complete a brief quiz.

Students solve six problems for series impedance using complex numbers. Immediate feedback is given.

In this animated object, learners read about hydrostatic pressure and observe how it is used to measure the level of a material in a container.

In this interactive object, learners view various components of gears and read descriptions of them. Learners then identify the location of each of these components in a drag-and-drop exercise.

Picture of Adira hydraulic shear's operator's panel with part identification and instructions on how to start and stop the shear as well as setting stroke (cutting length).

Introduces two methods of determining bend allowance; one is simple and is an approximate, the other is more precise. Interactive part has learner calculate bend allowance and blank size.

The learner reads about safety considerations for operating a hydraulic metal shear. Text, graphics and a brief assessment are included.
