(should be unique to your lab, both you and your partner can have the same title) Intro (less than a paragraph) This is where you give an introduction to your project; give a bit of background and a summary of the project. This should get the reader ready to read your report. Give enough information that they can easily follow your procedure and data. Do not put down your whole procedure here just some simple sentences explaining your self is fine in this section Setup (1 paragraph) This section deals with the problem you are trying to solve and your method for testing. Here is where you explain in detail what it is you are trying to test and how you are going to test it. Explain each step in your procedure, I should be able to reproduce your experiment from your setup section. Be sure to explain it properly, if you are unsure tell it to a family member and see if they can reproduce your experiment. Data (1 page) Here should be your data; the method of collecting your data should have been in the last paragraph so this should all be tables and graphs with only a few sentences to comment. All tables must be labeled correctly and all graphs must be labeled correctly. Do not just put 1 giant graph from excel, all graphs must have tables to associate the values too. (this can be done an a separate excel spreadsheet but must be titled the same as your lab report document.) Summary (1 paragraph) Explain and summarize your data, now that you have listed your data you can summarize the information. Take the numbers and tell me what they say. Do not impart your own opinions; just tell me what the data shows. Conclusion/Extrapolation. (1 paragraph) Here is where you impart your own opinion, take your data and make some predictions based on your data, what does it mean? Find a trend and apply your findings to things outside your project. Use journals on ebsco or Google scholar and cite your sources!
If you used any outside source to do your project (used a journal to research it, or referenced some book) be sure to note that in a bibliography and cite it in MLA format in your paper.
Improper citation could lead to a zero or plagiarism violation consequences.
How Gear Ratios Work by Marshall Brain
Yo u see gears in just about everything that has spinning parts. Car engines and transmissions contain lots of gears. If you ever open up a VCR and look inside, you will see it is full of gears. Windup, grandfather and pendulum clocks contain plenty of gears, especially if they have bells or chimes. You probably have a power meter on the side of your house, and if it has a seethrough cover you can see that it contains 10 or 15 gears. Gears are everywhere where there are engines and motors producing rotational motion.
In this edition of HowStuffWorks, you will learn about gear ratios and gear trains so you'll understand what all of these different gears are doing. You might also want to read How
Gears Work to find out more about different kinds of gears and their uses or you can learn more about gear ratios by visiting our gear ratio chart.
Putting Gears to Work
Gears are generally used for one of four different reasons:
1. To reverse the direction of rotation
2. To increase or decrease the speed of rotation
3. To move rotational motion to a different axis
4. To keep the rotation of two axes synchronized
You can see effects 1, 2 and 3 in the figure above. In this figure, you can see that the two gears are rotating in opposite directions, that the smaller gear is spinning twice as fast as the larger gear, and that the axis of rotation of the smaller gear is to the right of the axis of rotation of the larger gear.
The fact that one gear is spinning
