(C) Your students have learned that if two chords intersect within a circle, then the product of the segments of one chord is equal to the product of the segments of the other chord. That is, in the following diagram, ab = cd. Some of your more curious students want to know how that is proven. How do you do it? [Hint: Draw the dotted lines as shown in Figure 5.32, and try to get similar triangles.] R O b Figure 5.32 'S

The Unified Thread may have either a flat or rounded crest or root (Figure 4-6). If the sides of the Unified Thread are extended, a sharp V-thread is formed (Figure 4-7). In Figure 4-7, H is the height of a sharp V-thread. The pitch, P, is the distance between two adjacent threads. Find dimensions A, B, and C as indicated. a. H=716A=_,B=_ b. H=38A=_,B=_ c.

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.
