In one sentence, describe what the following article is about: If you're familiar with a manual transmission, the basic principles of the Eaton-Fuller Transmission shifterthe style used in many commercial trucks todayis similar, but more complex. Basically, it's oriented like a five-speed, but with a total of four different ratios at each position, which you toggle by a combination of switches and positions. This results in a total combination of 18 different speeds. The shift knob has two switches controlling air-actuated gears. One is the range switch, which needs to be set on "Low" for gears Lo-4, and the other is the high/low splitter, which is used to toggle between the low and high setting at each gear. Your index finger operates the range switch, which allows you to flip between high and low at each gear position with your thumb. Most gear shifts have a diagram displaying the shifting pattern, which will help to clue you into the organization of the gears. The low gears are usually differentiated from the high gears by color, and reverse is indicated by an "R." Gears 1-4 should all be straightforward, but then to shift into fifth gear, you shift back to the first position, and the pattern repeats. First gear is in the same position as fifth, second in the same as sixth, and so on. Remember, at each position, you also have a total of four different speeds, though only two will be accessible, depending on where you shift from. In first gear, you've got 1L and 1H, as well as 5L and 5H. This allows you to become familiar with the gear pattern so you can shift up and down without looking. This will help you keep your eyes safely on the road while driving. Grip the gear shift so that your index finger is available to work the range switch, and the middle and thumb can work the high/low splitter. If you don't have experience operating the clutch and driving a manual transmission vehicle, shifting a semi truck is going to have a much larger learning curve. Operating the gear shifter by itself is challenging enough, so you need to be very comfortable operating the clutch on a regular vehicle before you attempt to drive a semi. Practice on a regular car.
Summary: Understand how the gear shift differs from a normal vehicle's shifter. Learn the gear shift pattern. Practice the gear pattern of the semi while the truck is stopped.

In one sentence, describe what the following article is about: There are many different mandala crochet patterns available in crochet pattern books and magazines and online. Try browsing patterns for inspiration and guidance. You could follow a pattern to the letter to create a project you like, or you could follow a pattern loosely to make something based on the pattern. For example, if you find a mandala potholder pattern that you love, then you might want to follow it exactly as it is printed to get the same results. If you like the design, but not the colors, then select different yarn colors to use with the pattern. You can use any yarn colors you like to make your mandala. Choose a few colors to alternate back and forth between or choose several colors for a rainbow effect. You can use as many colors as you like, but choose at least 3. Bright colors will create a vibrant mandala, but you can also go with more subdued colors, such as pastels or neutral shades. For example, if you want a bright and colorful mandala, you could alternate between red, yellow, and orange yarn, or you could alternate between pink, blue, purple, green, red, and yellow yarn. If you want something more subdued, then you could try pastel shades, such as light pink, light blue, light yellow, and lavender, or alternate between tan, brown, and aqua. You can work a mandala using simple stitches like single and double crochet, or you can alternate between simple and decorative stitches. Try choosing a couple of decorative stitches to go back and forth between to give your mandala some intricacy. Some good decorative options include: Heart stitch Shell stitch Camel stitch Moss stitch Rosebud stitch The overall size of your project and the number of rounds you complete will affect the final size of your project. Each round will form a circle in the color you are using, and changing the yarn color more or less frequently will affect how wide the circles are. Try changing the yarn every 2 rounds for narrow circles, or every 4 rounds for wider circles. You can even alternate how often you change yarn colors to create a pattern of wide and narrow rounds. For example, you could start with a 2-round circle of yellow, then do a 4-round circle of blue, then a 2-round circle of red.
Summary: Check out mandala crochet patterns for inspiration. Choose your yarn colors. Select some decorative stitches to use. Make the circles as wide or narrow as you like.

In one sentence, describe what the following article is about: Slope is defined as "rise over run," with rise indicating vertical distance between two points, and run indicating the horizontal distance between two points. These can be any points the line runs through. You can also use this method if you are given two points on the line, without having the line graphed in front of you. Coordinates are listed as (x,y){\displaystyle (x,y)}, with x{\displaystyle x} being the location along the x, or horizontal axis, and y{\displaystyle y} being the location along the y, or vertical axis. For example, you might choose points with coordinates (3,2){\displaystyle (3,2)} and (7,8){\displaystyle (7,8)}. One point will be point 1, and one point will be point 2. It doesn't matter which point is which, as long as you keep them in the correct order throughout the calculation. The first point's coordinates will be (x1,y1){\displaystyle (x_{1},y_{1})}, and the second point's coordinates will be (x2,y2){\displaystyle (x_{2},y_{2})} The formula is riserun=y2y1x2x1{\displaystyle {
rac {rise}{run}}={
rac {y_{2}-y_{1}}{x_{2}-x_{1}}}}. The change in y-coordinates determines the rise, and the change in x-coordinates determines the run.
Summary:
Understand the slope formula. Pick two points on the line and label their coordinates. Determine the order of your points. Set up the slope formula.
