Exercise 4.4 Create and Implement a Basic Unit

For this exercise, you will be creating a basic unit that can be used to find a few measurements in an image. You will be working on the image below of the bottles. You will not be using measurements on a ruler, you will be creating a basic unit.

Materials needed:

Depending on if you have a printer or not, there are two different options available.

Option #1 – Preferred

• 4B pencil, Sharpie, or ball point pen – any type of pen that will show up on printer paper.
• A 8.5X11 inch print of the below image of bottles (in color or black and white) – The print should be as big as possible on the paper with minimum margins. For the exercise, you will add the necessary angles to the printed image and take a photo of it. Make sure all added angles show up on the image after you take a photo of it.

Option #2 This may work if you do not have a printer, however, it may be less precise and hard to fit everything. Keep it neat.

• Viewfinder and erasable marker
• Have the image of bottles pulled up on a computer monitor. Line up and place the viewfinder over the image on the monitor. Make sure the image is as large as possible in the viewfinder window. Draw the needed information on the viewfinder with your wet or dry marker.  Take a photo of your monitor with the viewfinder aligned and attached with the finished work on it.

Time to complete: 20 minutes. Use the full 20 minutes to work on this exercise.

Instructions:

1. In the image below, use the width of the bottle on the far left to establish a basic unit.
2. Use the basic unit you obtained from step one and find how many basic units across all nine bottles are together, from the far left edge of the bottle on the left to the far right edge of the bottle on the right.
3. Mark the ends of each basic unit similarly to the marks on a ruler and number them.                      Example: |1|2|3|4| etc.
4. At the bottom of the page, write down the total width you think it is and get to the closest half unit. Example: Width of all bottles combined is 135 1/2 units.
5. Using the same basic unit calculated in step #2, find the height and width of the second bottle from the left (the tallest one). Show marks for these measurements on the bottle that is second from the left.

Group the photo of your finished image with exercises 4.2-4.5 in one file when submitting your work. Do not submit exercises 4.2, 4.3, 4.4, and 4.5 as individual files. If using a viewfinder, take individual images of each exercise and combine them into one file.
