Three holes are bored in a checking gage. The lower left edge of the gage is the reference point for the hole locations. Sketch the hole locations and determine the missing distances. From the reference point: Hole #1 is 1332 to the right, and 158up. Hole #2 is 2164 to the right, and 2316up. Hole #3 is 314to the right, and 312up. Determine: a. The horizontal distance between hole #1 and hole #2. b. The horizontal distance between hole #2 and hole #3. c. The horizontal distance between hole #1 and hole #3. d. The vertical distance between hole #1 and hole #2. e. The vertical distance between hole #2 and hole #3. f. The vertical distance between hole #1 and hole #3.
It is sometimes impractical to make engineering drawings full size. If the part to be drawn is very large or small a scale drawing is generally made. The scale, which is shown on drawing, compares the lengths of the lines on the drawing to the dimensions on the part. A scale on a drawing that states 14=1means the drawing is one-quarter the size of the part. It is expressed as a ratio of 1:4 or 14 . A scale drawing that states 2=1means that drawing is double the size of the part. It is expressed as a ratio of 2:1 or 21 . The actual dimensions of a steel support are given in Figure 20-11. All dimensions are in inches. Using the proportion given, compute the lengths for each unknown in the table. Round the answers to 3 decimal places where necessary.

Spache Readability Formula The Spache Readability Formula3 is designed to categorize reading materials for grades 1 through 3. For a passage of text, the variables are S, the number of sentences: W, the number of words; and U, the number of unfamiliar words words not on a specific list. The formula as revised for the grade level is Grade level =0.121WS+0.082U+0.659. The calculated grade level is rounded down to its whole number part. For example, 2.6 is round down to 2. In this exercise, we consider passages having 200 words and using 10 unfamiliar words. a. As the number of sentences increases, does grade level increase or decrease? b. What is the maximum possible number of sentence? Can there be more sentences than words? c. What is the minimum number of sentences that would put this passage at the second-grade level?
