In this interactive object, learners read the common abbreviations used in engineering drawings and then test their knowledge in three short exercises.

After a brief review, the student solves five practical shop problems using right angle trigonometry.

In a series of three interactive exercises, learners explore the relationship between process cycle time and defect detection, and between process cyle time and smaller batch sizes. The techniques of lean/JIT are applied to achieve the continuous improvement (kaizen) goal of reducing inventory by pursuing one-piece flow.

Learners study factors that affect the synchronous speed of an AC motor: the applied AC frequency and the number of stator poles.

In this animated and interactive object, learners use a memory device to identify NPN and PNP transistors. Learners also examine how much the transistors turn on when the voltage applied to the base is varied.

By playing a game of tic-tac-toe, a student can review what happens to currents and voltages throughout a series RLC circuit when the applied frequency is increased from 0 Hz towards resonance.

This learning object reviews the procedures for making medical appointments. It can be applied to manual and electronic methods of making appointments.

Learners view animations showing how electrical signals are applied to the coils of a stepper motor to perform microstepping. A short quiz completes the activity.

Learners examine how voltages and currents vary in a series RLC circuit as the applied frequency changes.
