In this screencast, learners follow steps to determine the proper starting belt length for a timing, flat, or v-belt drive.

Learners read how the RL 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.

Users calculate the tonnage required to punch holes in a specific base metal. The formula to be used is provided along with the tensile strength for various metals. A calculator is required.

Students solve five problems to determine the total impedance of a series-parallel circuit. Immediate feedback is given.

In this screencast, students read about the stages of microbial dental plaque formation and the time it takes for each stage to occur.

The student will read a mini-lecture explaining the organization stage in the perception process and will complete an activity.

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.

Students view several examples of how to determine the total impedance of a series circuit. The "j" term is used in all of the calculations.

In this learning activity you'll calculate problems using the negative both inside and outside of the parenthesis.

Learners read how to use the knobs and the output terminals of a Wavetek Model 25 function generator to obtain a waveform at a desired frequency.

In this learning activity, you'll explore the basics of prototyping for user experience design.

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

In this screencast, learners examine the kinds of physical and chemical changes that occur in substances.

In this screencast, we review the positions of metals, metalloids, and nonmetals in the Periodic Table and the general characteristics of each.

Learners study the operation and characteristics of an incremental optical encoder used in automated manufacturing applications. A brief quiz completes the activity.

Students work practice problems in which the total resistance of the circuit is calculated. Feedback is provided.

Students read about the common characteristics of the Junction Field Effect Transistor. They also explore the schematic symbols and the basic operation of the JFET.

Learners examine the anatomical parts of the lungs.

In this animated activity, learners view the following physics concepts in action: force, friction, horsepower, work, power, inefficiency, resistance, inertia, and energy.
