The purpose of this paper is to review on how physics can help to improve motorcycle performance. I currently own a 2003 Harley Davidson VROD. It came from the factory weighing in at 683.3 lbs (dry) or 285 kg. The VROD has a wheelbase of 67.2 inches or 1710 mm. The Engine that resides in the VROD is an 1130cc German designed performance engine developed by Porsche that has a winning stature in the racing world. The VROD is claimed to have a 115 horsepower or 86 kW of power at 8250 revolutions per minute (rpm) at the crankshaft. It also claims to have 84 foot ponds of torque or 113.9 N-m at the crank. All that information translates into that the VROD line of motorcycles are long, low, and very fast compared to other larger displacement motorcycles of that style. With such a high tech engine, I feel that more power can be tweaked out of it to help improve miles per gallon (mpg) horsepower, and torque. We will first begin with air intake performance. A stock air flow filter allows a set amount of air flow to pass thru the combustion chambers of the engine. But as we all know more ai...
The Reason that people need a tank when they play paintball is because you need a way to force the paintballs out of the gun and this cannot be achieved effectively by just using a spring. What they decided to do was to fuel the paintballs by pushing them with a gas. The way in which they did this was to put the gases, either Oxygen, Carbon Dioxide or Nitrogen under extreme pressure until they turned into a liquid and once they are in a liquid form they can be blown into a tank which probably looks something like this.
There are three main areas of paintball that I will be analyzing. First the way in which a paintball leaves the barrel of a paintball marker. Second the way in which a paintball fly's through the air and lastly how to determine optimum ranges for paintballs.
There are many ways to analyze the performance of a company, some more popular than others. According to the Barney text the accounting method is the most popular way of measuring a firm's performance (Barney, 2002). Some of the reasons for the popularity could include the fact that accounting measures of performance are publicly available on many firms and they communicate a great deal of information about a firm's operations. Other methods of performance analysis include firm survival and the multiple stakeholder approach.
Harley Davidson’s approach to the manufacture of motorcycles creates value as raw materials evolve into sellable products. The 40,000 square meter plant in Kansas City, Missouri is laid out in a fashion that permits the backward integration of components within the production facility. From the fabrication of parts to the production of engines onsite, a single V-Rod is built by the 1,100 employees of this factory in less than 3 hours from start to finish.
The Physics Behind the Power of an Engine Insert the key, turn, and vroom. And down the road you go. Most people take for granted the strange conglomeration of metal and plastic under that sheet of metal, either in front or back of their vehicle. The engine, as you may have guessed, is a modern marvel- so to speak. They’re found in cars, trucks, boats, airplanes.
The admiration of Hybrid cars in the United States market to this day is increasing at a rapid rate. Hybrid cars have been in high demand by buyers all over the United States. As time progresses, more and more consumers grasp that the upcoming hysteria of hybrid vehicles are not only better for the environment, but are all around much economical to our prodigious populace. The growing popularity of hybrid cars is due to an increase in the diverse archetypal choices available, the time-tested expertise and the economical valuing. A vehicle is deliberated as a hybrid if it utilizes more than one form of energy to attain momentum. With a customary internal-combustion engine and fuel tank, as well as one or more electric motors and a battery pack, this makes this type of vehicle is considerably dissimilar than other Hybrid’s out there.
he TriFit system was designed by Polar, the technological innovators in heart rate monitors since 1977. Polar, which was once known as Healthfirst, swtiched its name to Polar in the 1990's which is when it developed the firt model of the Trifit software. The first EKG accurate wireless heart rate monitor was invented by Polar back in 1977 as a training tool for the Finnish National Cross Country Ski Team. The concept of "intensity training" by heart rate swept the athletic world in the eighties. By the 1990's individuals were looking to heart rate monitors not only for performance training needs, but also for achieving everyday fitness goals. Today, the same concept of heart rate training is being used by world-class athletes as well as everyday people trying to lose weight.
"Harley-Davidson: At Last" as presented in Hartley's Marketing Mistakes and Successes presents the circumstances around HD's near collapse and since rinse to near mythic success. This case is a great example of marketing myopia; HD saw them-selves as full-size motorcycles' manufactures, not in the transportation, or even the entertainment industry. They believed no one bought motorcycles for transportation, but rather for leisure time use.
The aerodynamic efficiency is the single most important element in designing a competitive car for professional racing or getting the car model on the front of a Car and Driver or Motortrend. Aerodynamics is the study of the motion of gases on objects and the forces created by this motion. The Bernoulli effect is one of the most important behind car design. The Bernoulli Effect states that the pressure of a fluid, in gaseous or liquid state, varies inversely with speed or velocity and a slower moving fluid will exert more pressure on and object than the same fluid moving slower (Yager). The goal of car designers is to make the air passing under a car move faster than the air passing over the car. This causes the air passing over the car to create more downforce than the air passing under the car creates upforce creating a force additional to the car’s weight pushing the car to the road. Large amounts of downforce are needed to keep light cars grounded at high speed and keep to cars from sliding around turns at high speeds.
This paper is a look at the physics behind car racing. We look look at how we can use physics to select tires, how physics can help predict how much traction we will have, how physics helps modern cars get there extreme speed, how physics lets us predict the power of an engine, and how physics can even help the driver find the quickest way around the track.
This paper is being written to identify and provide demographic information on a population that has been through trauma and resiliency following motorcycle accidents. This population has been through some form of trauma whether they realize it or not. Some people deal with trauma differently. For example, many motorcyclists engage in drug and alcohol to feel most comfortable because they face traumatic situations on the road, daily. Many of the traumatic experiences are caused by automotive drivers. According to “Nolo” (2016), Crashes involving motorcycles and other vehicles account for fifty-six percent of motorcycle accident deaths. In the vast majority of these accidents, the car strikes the

Harley Davidson has surpassed 100 years and continues to grow and move forward. As a company that started in 1903, Harley Davidson has become an icon of American motorcycles. Harley Davidson’s ideals of freedom and self-expression have transcended cultures, gender, and age (www.harley-davidson.com). The company has the purpose of fulfilling dreams of personal freedom of individuals which has translated into a very well-known brand and culture.
Hybrid vehicles first came on the seen to create super efficient cars to combat rising fuel costs and offer more environmentally friendly alternatives to traditional combustion vehicles. The hybrid vehicle concept is that there are two motors at work, one is traditionally a gasoline engine paired with a small battery powered electric motor. Each manufacturer’s hybrid power-train varies, but the main benefits gained from the addition of an electric motor and battery pack, is that the electric motor adds free power from the battery pack in the car to aid in acceleration and
In my undergraduate years, I have acquired a strong background in the fundamentals of basic mechanical engineering, having studied subjects such as Strength of Materials, Thermodynamics, Fluid Mechanics, Heat and Mass Transfer, Design of Machine Elements and Automobile Engineering. Whilst pursuing my diploma & degree courses, my interest for Automotive Engineering grew even more having learnt more on the different types of internal combustion engines, their configuration and importance. However, what I lacked was a practical understanding on these core areas of Automotive Engineering. To gain a better understandi...
