Students can use the three different gears to compare the partial revolution of one gear to the whole revolution of another. Ratios can be determined using rotations and / or the number of teeth on a given gear.
Automotive, heavy-duty, and agriculture technicians must understand of gear systems and ratios as they work on transmissions for vehicles and power trains for vehicles and implements.[/vc_column_text][/vc_column_inner][vc_column_inner width=”1/3″][vc_column_text css=””]L’heure

Preparation
- Each gear set comes with three different gear sizes, a board, and a handle. Check each gear set to make sure all components are accounted for and in working order.

- Introduce the gear set to students by demonstrating that the gears can be removed from the board and relocated to a different position.
[/vc_column_text][/vc_column_inner][vc_column_inner width=”1/2″][vc_column_text css=”.vc_custom_1729106517103{background-color: #f5f5f5 !important;}”]
- Explain that part–whole relationships can be demonstrated by counting the number of rotations one gear makes in relation to another based on whole revolutions or, to be more exact, by counting the number of teeth of each gear.
[/vc_column_text][/vc_column_inner][/vc_row_inner][vc_row_inner][vc_column_inner width=”1/2″][vc_column_text css=””]
- Students can then rearrange the order of the gears on the board and write a ratio based on the new gear placement.

- Students can also rearrange the placement of the handle, varying their drive gear in each gear train that is created.

Suggestions d’évaluation
[/vc_column_text][/vc_column_inner][/vc_row_inner][vc_row_inner][vc_column_inner width=”1/2″][vc_column_text css=””]
Written assessment
- Students write the different gear trains as a ratio in a workbook.
[/vc_column_text][/vc_column_inner][vc_column_inner width=”1/2″][vc_column_text css=””]
Extension
- Students can explore the concept of mechanical advantage as it relates to the size of gear being the drive gear in the gear train.
