XYZ Unit Vector, 1A30.10

Topic and Concept:

• Measurement, 1A30.Coordinate Systems

Location:

• Cabinet: Mechanic (ME)

• Bay: (A3)

• Shelf: #1

Abstract:

Aluminum stand that holds 3 arrows to show Cartesian unit vectors.

Important Setup Notes:

• N/A

Setup and Procedure:

1. The aluminum stand can be used alone to demonstrate the unit vectors.
2. Otherwise, insert an arrow into each of the three holes on the aluminum stand so that the tips point outward.
3. Using the model unit vectors, explain how a 3D Cartesian coordinate system works.

Cautions, Warnings, or Safety Concerns:

• N/A

Discussion:

The Cartesian coordinate system is widely used in physics and engineering. The spherical and cylindrical coordinate systems are usually based off of the Cartesian unit vectors.
