Pierre Michaux and his brother Ernest developed the front-pedaled velocipede in 1855. They were iron workers who opened a carriage shop in Paris (Perry 19). Together they began experimenting with bicycles and came up with the idea of putting the crank on the front wheel. When they had successfully created the front driven velocipede they organized factories in France to produce their product. They refined the frame design and began to make velocipede out of iron rather than wood. In their new design, the front wheel was larger than the rear wheel. This was because the pedaling force was on the front wheel. This design made steering the velocipede somewhat awkward because the rider's leg would constantly be hitting the front wheel as the rider was turning. Pierre Michaux was the person credited with popularizing the velocipede in Britain, the US, and France (Perry20). The bike design was now improved with steering and pedaling systems. Finally, as gearing systems were developed in the early part of this century, the basic design of the bike was complete.
The first and most important part of the bike is the frame. The frame is the basic support and design of the bike. The frame is made up of a front and rear triangles, and if the triangles are formed it makes a parallelogram. A parallelogram is a four sided plane figure with opposite sides parallel. The front triangle actually forms into a shape of a quadrilateral. That is a plane figure having four sides and four angles (Encarta 97 Encyclopedia).
The second part of the bike is the wheels. The wheel provides energy, movement, and direction. The larger the size of your wheel, the more distance you get for every rotation of the wheel. This is proven by using the formula for the circumference of a cycle C = Diameter * PI (Smith, 242). For example 26 inches is the diameter of a wheel on a bicycle, using the formula for the circumference of a circle, you can find out that 81.
Do you agree or disagree with the following statement? It is more important for students to study history and literature than it is for them to study science and mathematics. Use specific reasons and example to support your opinion. Students take lessons in diverse subjects in school. As their g...
Music and mathmatics were also studied as well. ... Many artisans merged mathmatics with art , in order to become more precise in their measurements and to make sure an object was supported both rationally and porportionally. ...
Algebra 8 Derek Harms I thought that this semester was easier than what it looked like it would be but it still was hard. I enjoyed the challenge and thought it was very interesting to be in your class. My favorite part was the end of the first quarter when we had to find the mathmatics of dif...
Knowing about the Bohr atom, isolated atoms can absorb and emit packets of electromagnetic radiation having discrete energies dictated by the detailed atomic structure of the atoms. ... The emission lines correspond to photons of discrete energies that are emitted when excited atomic states in the gas make transitions back to lower-lying levels. ...
.); the second part -from line 15 to line 21- would rather deal with books (in there, Bacon describes the different types of books that there are); the third part would take from line 21 to line 27, and in that part, Bacon identifies the different sciences with the different skills that those sciences help us acquire: "Histories" make you wise, Mathmatics make you subtle, etc.); finally, the fourth part, which would go from line 27 to the end, can be taken as a conclusion, as quite an optimistic conclusion since it tells that we can make whatever we want to, by means of practice and investigat...
