Analysis of Hurdling Mechanics Brian Fuentes Lynchburg College The purpose of this paper is to analyze the motion and mechanics of hurdling during the 100 and 110m hurdles in order to better understand the proper technique to clear the barriers. When analyzing hurdling technique it’s important to consider proper body mechanics in order to understand the motion of the skill. While athletic ability is an important factor for this race‚ proper technique is more important for running

both standard & metric units of measurement as well for most all aspects of automotive repair‚ including electronics. Being an automotive mechanic can be a very rewarding career if you like challenges and the sense of pride in doing the job right the first time as people’s lives may depend on the quality of your workmanship. If you decide against this as a career‚ it also pays to learn as much about your car as you can so you do not have to pay someone else like me to do it for you. ;-) Other fields

very different motor from a gas or diesel engine. Instead of fuel‚ it uses a lot of batteries. Since it has no fuel‚ it uses no emissions‚ which makes it much more eco-friendly. It also is a lot cheaper to use electric cars than a gas car. An electric car can average around 1 cent per mile‚ while at $2.20 a gas engine averages 8 cents per mile. An electric engine also has much less power than a gas or diesel engine. They also cant go nearly as far as a gas or diesel engine due to the batteries being

Nicholas Caruolo Throughout my life I’ve always had an interest in mechanics. At a young age I was constantly taking things apart to learn how they go together. This mechanical interest has played a huge role in life‚ dictating my hobbies and interests. My job as a bicycle mechanic is a large interest of mine. It allows me to creatively use my mechanical knowledge to fix problems with bicycles. Outside of work‚ I recently bought a motorcycle and have since been disassembling and tuning the entire

A diesel engine (also known as a compression-ignition engine and sometimes capitalized as Diesel engine) is an internal combustion engine that uses the heat of compression to initiate ignition to burn the fuel‚ which is injected into the combustion chamber. This is in contrast to spark-ignition engines such as a petrol engine (gasoline engine) or gas engine (using a gaseous fuel as opposed to gasoline)‚ which uses a spark plug to ignite an air-fuel mixture. The engine was developed by Rudolf Diesel

Diesel Engines Diesel engines are everywhere; they are used in all sorts of vehicle platforms. From Volkswagen Jetta’s‚ to big eighteen wheel tractor trailer trucks. They provide more torque then a regular gasoline engine because of the long stroke of the piston. Most diesel engines make peak torque at very low rpm. Diesel engines do not have spark plugs. They develop combustion by heating up the air going into the cylinder‚ while the air is heated the fuel injector sprays into the bowl of
