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

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.

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

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

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 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.

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

In this animated object, learners examine a closed-loop feedback system that uses digital circuits to control the position of a gear rack.

In this animated object, learners examine an analog closed-loop feedback system that uses potentiometers to control the position of a gear rack.

Learners consider whether to lease or purchase equipment based on return on investment. This activity is geared toward operators of a dairy farm. Two pages contain audio.

Learners apply lever ratios to calculate the mechanical advantage in basic mechanisms.
