Transcript of The Bicycle
a Scottish blacksmith, is
generally credited with
inventing the bicycle
in 1839, however,
there is speculation
that it could have
been invented earlier. http://kids.britannica.com/comptons/art-125139/The-first-self-propelled-bicycle-was-made-by-Kirkpatrick-Macmillan http://wiki.answers.com/Q/Why_was_the_bicycle_invented What the Bicycle Does Before the bicycle was invented people had two ways to get from place to place. Either they would ride on the back of an animal or walk. The bike was originally made as a toy for rich people. It is now used as a fun activity or a way to exercise. Innovations of the Bicycle British engineer James Starley made the Penny Farthing, a more efficient version of the bicycle. http://inventors.about.com/od/bstartinventions/a/History-Of-The-Bicycle.htm 1871- 1885- 1905- John Kemp Starley designed the first "safe" bicycle, with a steerable front wheel. Paul de Vivie created the first bike with multiple gears. http://en.wikipedia.org/wiki/Derailleur_gears Sources: How the Bicycle Relates to Engineering, Science, Math, and Technology Bicycles are full of fascinating gears, levers, bearings, fulcrums, pivots, thrust, and other nifty stuff. All of these are components in engineering.
Although engineering plays a big role in the creation of the bicycle, science also has a a strong voice in the process. In order for the bicycle to move it relies on momentum and inertia. If it wasn't for these two scientific theories the bicycle would probably not be here today. Science and engineering are not the only elements that go into the making of the bicycle. Quote on the Bicycle http://www.ibike.org/library/science.htm Negatively: The bicycle is very affordable and does not cause as much pollution as a car. It is good exercise, and is a simple way of transportation. The bicycle has created jobs, with bike shops, repair shops, and manufacturing. http://formulas.tutorvista.com/physics/static-friction-formula.html While riding a bike you run the risk of getting seriously injured. There is a very limited carrying capacity, unlike walking or driving in a motor vehicle. The bicycle also comes with an increased crime rate from people stealing bicycles. Math also contributes to the procedure. If we didn't have friction the wheels would slip on the ground. Making it almost impossible to ride. This is Static friction because the wheel is not moving relative to the ground. The mathematical formula for friction is Fs = Us Fn. Although we have covered most of the main factors in making a bike there is still one other one that you should know.
Technology has helped the bicycle in a very positive way. With technology we have been able to improve the wheel and have multiple gears, when in the past bicycles used to be single geared. The grips on pedals and handles have also been improved. How Has the Bicycle Impacted Society? What Area of Technology Best Classifies the Bicycle? The bicycle is best classified as a type of transportation. The bicycle allows you to get to nearby places in a small amount of time. On average the bicycle is three times faster than walking. Although, riding a bike will take much longer than any motor vehicle would take for the same distance. "Life is like riding a bicycle - in order to keep your balance, you must keep moving."
~Albert Einstein http://www.quotegarden.com/bicycling.html Bicycle Innovations Futuristic Innovations Fun Facts 1. In 1817, there was a bike like machine. It had two wheels and no pedals. To operate the machine you would push off the ground with your feet. 2. In the 1860s the bicycle wasn't named the bicycle. They simply called the bike a two wheeled machine. 3. The Wright brothers who built the first flying plane, operated a small bike repair shop in Dayton, Ohio. They used their shop to build the 1903 Wright Flyer. http://kids.nationalgeographic.com/kids/stories/morestories/ten-things-about-bikes/ folding bike helmet http://blogs.phoenixnewtimes.com/jackalope/2012/08/bicycle_innovations_future_of_cycling.php?page=2 invisible bike helmet http://www.pedalinghistory.com/Images/Draisine.gif 4. 7/8 of all Dutch people over the age of 15 own a bike phone charger foldable bike 5. Americans use their bicycles for less than one percent of trips in the city. Europeans bike in cities a lot more often; in Italy 5 percent of all trips are on bicycle, and 30 percent in the Netherlands. http://www.carreraworld.com/us/editorials/foldable-helmet http://www.takepart.com/photos/bicycle-innovations-could-change-world
