Physics of a Mountain Bike Essay example -- Physics Papers

Physics of a Mountain cycle This paper bequeath discuss some of the physics involved in bicycles. Specifically, mountain bikes with suspension. A bicycle is a very energy efficient vehicle. Its wheels allow its passenger to make full use of inertia and gravitational potential energy. The basal design of a bicycle has been around for over 100 years and comp ard to other things, has changed very little. about of the topics that will be covered are marchs, wheels, suspension forks, suspension frames, brakes and how all these things affect speed, momentum and stability.Some of the key parts of any bicycle are the frame, forks and wheels. The most reciprocal type of bicycle frame is known as the double diamond. It is called this because if you count on at the frame, it is diamond shaped with 2 smaller triangles forming the front and rear. This designed has endured because it is easy to build, strong and efficient. The tubing that a frame is made with is unremarkably round but can be many different shapes all the same on the same bike. The reason for this shaping is to increase the rigidity or improve the ride quality. For instance, the sloping tube that goes from the front of the bike to the pedal junction of the frame is sometimes ovalized along the horizontal axis at the pedal junction to make the frame flex less array to side. Frames have been made from many materials including wood, steel, aluminum, titanium and carbon fiber adept to name a few. Each of the materials have a strength to tilt ratio, tensile strength and cost of production that must be interpreted into account before deciding which will work best. For example, when a frame made of beryllium was introduced, the strength to pitch ratio was very high. The weight was extremely low but the cost wa... ...etty. The debaucheder you go, the smoother it gets and the great the force required to stop. Mass times velocity is not dramatic play when applied to a crash. Mike Farrentino in an art icle in Bike powder magazine says, The faster you go, the longer the crash, the greater the force of the impact. Seconds seem give care hours, and the clatter and gasp and thud of cart wheeling bike and physical structure parts is not a sound easily forgotten. In ache of this, whatever any of us say, we all want to go fast.Momentum is the secret key to the universe. It is the rush of joy. It is the heavy hand of gravity. It is the grin of a child, feet off the pedals, bombing downhill on a tricycle.SourcesBike magazine volume 10, number 2 March 2003Bloomfield, Louis A How things work, the physics of terrestrial life, 1997 Kirkpatrick & Wheeler Physics, a world view, third edition, 1998 www.howstuffwork.com
