 Learn how to build bikes

1. What kinds of metals are best-steel,aluminum, titanium 2. How and where do I weld-wherever there are bends or curves that is going to hold stuff 3. How to make a bike design- take a bike and build a design around it 4. Where is the best place to paint a bike- inside where there is no dust flying around 5. How strong should the welds be- depends on how thick the materials are 6. What type of paint should i use- depends on how you want the paint to come out 7. How big should the bike be- as big as you want it to be 8. How much power should the welder be set to-depends on what kind of welder you have 9. where is the best place for a curve-? 10. What are good bike styles- anyway you want it to be

 * Article #1 How to build a bike **

this article is mostly about how well different materials ride, wich material is bst for a bike, different kinds of stiffnesses that are upon a bike, how thick tha inner walls of the materials should be and lot's of info on where comfort comes from, how to improve comfort, and how to repair different types of materials.

1. that there are different types of stress on a bike 2. strength is determined by a propertyof the material called "yield strength" 3. a bike with a "lite steel" sticker is actually the same weight as other bikes 4. there are no carbon fiber frames for long tour rides

I enjoyed reading this article because it gives me information on just about everything i need to know about different types of materials. this article gives me allot of info on different types of stresses on a bike and were there are weak points. and where comfort comes from and how thick a tube wall should be.

= Annotated Bibliography =

In this article i learned about stiffness and ride quality's,ringing damping and suspension, where comfort comes from, the strength and weight and about how different materials differ from one another.

 * Napier, Jeff. "a tutorial for bicyclist" in "www.bikewebsite.com/weld.htm"5-9-11 **

In this article i learned about what precautions to take when welding and what to expect when welding.


 * Putnam, Josh. "How do i design a bike frame" in "www.phred.org/~josh/build/design.html"5-9-11**

In this article i learned about building a custom bike frame that is designed around my leg length, torso length, arm length and my preferred riding position.


 * Expert project introduction **

My project is based on making a bike that is built around my height and weight. I decided that I would learn to make bikes because I like to build stuff and I like to ride my bike when I have any free time. so why not learn to build a bike when both catagories fall under ,learning how to build a bike, so why not learn to make a bike that has just been a thought.weld by weld the thought would slowly start out as a few metal tubes welded together finally turning into what would become a bike built around an idea.

vocab words

 * Article of the week #1 response **

I think that being plugged in does't necesserily make us dumber but it distracts us from how we could have fun like back then. I think that a solution to the problem of the Pitts would be that they could alternate between bieng plugged in and being plugged out. I don't agree with the Pitts but being plugged in does distracts us from being able to have fun without electronics.


 * summary of article #3 **

"Long spells at screen create health risk" was an article that I read that talked about the effects of prolonged computer and television use on the human heart. The chances of having heart problems when four or more hours a day are spent in front of a computer or television screen. It was thought that exercise could reduce the chances of heart problems, but now it is said that it makes no difference. The problem is from the body's inability to create enzymes called lipoprotein lipase, wich helps to break down cholesterol. This enzyme is not created during periods of low or no activity. as shown sitting in font of a tv or computer screen is low activity.

4 things I learned

1st thing I learned was that sitting for too long in front of a screen could cause health problems 2nd thing i learned was thatwhile sitting for long periods of times reduces the body's ability to make enzymes called lipoprotein lipase witch helps to break down cholesterol. 3rd thing i learned was that doing exercice makes no difference in the prolonged sitting. 4th thing I learned was that maybe even going and coming from work could be a health risk

opinion

I think that it would only applie to adults because us as teenagers we have more energy letting us do more exercise and having more time to sit down in front of any kind of screen.
