In this video, you’ll learn how to make changes to an engine lathe.

In this screencast, learners examine the concept of gear ratios. The number of teeth, diameters, and velocity relationships are discussed and calculated using linear ratio equations.

The learner will understand the design of a planetary gear drive and its advantages and disadvantages.

Learners read an analogy comparing an electrical transformer to mechanical gears.

The learner will understand the inner workings of the strain wave gear principle.

Learners examine the fundamentals of a pulse train. Concepts such as time on, time off, duty cycle, period, and frequency are covered.

The learner will gain an understanding of the inner workings of the cycloidal gear drive while watching a video and listening to an explanation of its features.

In this interactive object, learners determine the pulse width, period, duty cycle, and frequency of a waveform.

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.

Learners examine how the two-roll metering system works.

Learners read descriptions of the following training and certification levels for organizations using a lean approach to quality: "green belt," "black belt," "master black belt," and "champion."

This project gives a drawing with steps to complete the activity.

Learners read about the role of water, the basic physiology of water balance, and the effects of dehydration particularly on elderly clients. Tips for maintaining proper hydration are presented. In an interactive exercise, students calculate how much fluid a client needs based on his/her age, health, and weight.

Learners follow the path of a protein food from consumption through digestion to absorption into the bloodstream.

Learners take a close look at the information on product labels concerning fat, fiber, and serving sizes. A quiz follows the lesson.
