An automobile assembly line worker is required to read the specific letter from a sheet that is taped on the vehicle at about shoulder height and hangs approximately vertically. Each worker has a relatively limited section of the line (6 to 8 feet) in which to work. S/he cannot work up or down the line very far, or s/he will interfere with the activities of the next worker. Answer the following questions and make sure to include the calculation steps: 1. Assuming that the current stroke width of the letter that needs to be read is 0.018 inches and the worker has a normal 20/20 vision, what is the maximum reading distance (in feet) under these conditions? (5 pts) 2. Assuming that the same worker has to stand about 7 feet away to pace the work comfortably and efficiently, how big should the letter be (in inches) if the stroke width to letter height ratio is 1:72 (5 pts) 3. Assuming that the letter is boldface type with a 1:5 stroke width-to-height ratio and the worker has a 20/30 vision, how big should the letter be (in inches) if the worker reads from 7 feet away? (5 pts) 4. List 4 examples of factors that may affect distance reading and use your own words to give a definition to each of them. (4 pts) 5. Given the results of your calculations and any necessary assumptions, describe 3 examples of design recommendations that you should make for this task. (6 pts)
