greater mechanical advantages than simple machines. There a two types of mechanical advantage. They are ideal mechanical advantage (IMA) and actual mechanical advantage (AMA). IMA is the input distance divided by the output distance. For inclined planes it is the length of the inclined plane divided by the height of it. AMA is the output force divided by the input force. If the mechanical advantage is greater than 1, they are force multipliers and displacement or speed dividers. If the mechanical advantage
get work done. Mechanical advantage is how much input work is applied to machine compared to the output force put out by the machine. The mechanical advantage calculated by taking the actual measurements of the machine, such as length and height and displacement, is the ideal mechanical advantage or IMA. The mechanical advantage of a machine is calculated using the actual forces applied to the machine and force output from the machine. This is called the actual mechanical advantage or AMA. The AMA
Inclined planes are yet another simple machine that you use nearly every day. Any time you walk up a slight hill, you are using an inclined plane. Any time you ride your bike or drive your car up a hill on the way to school, you are using an inclined plane. Even when you push your grandma in her wheel chair up the handicap ramp you are using an inclined plane. So to summarize what an inclined plane actually is, it is a flat surface on an angle that is always used to multiply your force. BUT WAIT
In the competition known as Science Olympiad, there is an event build called “Boomilevers.” This event is comprised of building a structure to be attached on one side to a wall and bear the maximum weight possible on the other side, while the structure itself weighs as little as possible. The Boomilever is a long standing Olympiad Event and requires acute attention to detail and a critical mind in architecture in order to achieve the maximum efficiency score possible. There are many limitations and
Purpose The machine is a Rube Goldberg machine that turns on a light. It has no practical purpose, and exists solely as art. It is exciting and beautiful to watch, but a machine that takes three times as long to do a task that requires very little effort without a machine has no inherent value. It is simply there as art, as something for people to look at and to enjoy. A Rube Goldberg machine is witty. People like seeing how parts just fit together, how a chain reaction of small parts can do something
The Physics of Dip Netting Introduction to Dip Netting Dip netting for salmon in the Copper River is a lot of fun but is also a lot of work.� During the summer months salmon will leave their home in the ocean and travel upstream in the Copper River to spawn in its many tributaries.� Near the small town of Chitna the Copper River flows through a narrow canyon which greatly increases the speed of the river.� This makes it harder for the salmon to swim upstream.� However the canyon also creates
I was startled by my monsters question. Closely I examined his option, hoping the creature would not lash out on him for taking so long. I agreed, but on the terms that the wretched creature and this new one will no longer physically harm anyone and stay away from sight. My creature tensed as if he knew this would come up. His eyes looking dreary, along the sides stitches healed into long, thick scars. Reluctantly, he agreed. My monster was wide-eyed with his mouth agape, obviously surprised by this
a force. Simple Machine- A device that performs work with only one movement. Simple machines include lever, wheel and axle, inclined plane, screw, and wedge. Ideal Mechanical Advantage (IMA)- A machine in which work in equals work out; such a machine would be frictionless and a 100% efficient IMA= De/Dr Actual Mechanical Advantage (AMA)- It is pretty much the opposite of IMA meaning it is not 100% efficient and it has friction. AMA= Fr/Fe Efficiency- The amount of work put into a machine compared
The Advantages of Superchargers and Turbochargers: Types of Forced Induction The light turns red and you slowly come to a stop driving your 1992 GMC Syclone equipped with a 280 horsepower 4.3 liter V-6 teamed up with a four speed automatic transmission. The GMC Syclone is basically a sporty run-off of GMC's Sonoma. In the next lane, a brand spanking new Ford Mustang equipped with a 320 horsepower 4.6 liter V-8 pulls up. You seem to be feeling pretty spunky today, so you rev your engine signaling
who are passionate about getting their hands plastered in motor oil, grease, and other mechanical lubricants. These people will more than likely be ecstatic about getting into industrial machinery mechanics. They need to be able to put in one hundred ten percent of their effort into becoming an industrial machinery mechanic. An industrial machinery mechanic’s overall objective on the job is to stop a mechanical error before it happens. An industrial machinery mechanics are often caught repairing,
How Dole Could Have Used The Issues To His Advantage In a more or less conservative country, the more or less conservative candidate, Bob Dole, should have been a lock for the presidency; the only problem was President Clinton. Clinton had moved rightward positioning himself between Newt Gingrich's zealous revolutionaries on the right and liberal democratic barons on the left. Clinton's speeches started sounding like a Republican was giving them. Bob Dole had followed the Nixon ideology of going
The Advantage of Commercials It began in the early 1940's and to this day still is in many of our lives, even more so then before. It's the TV that I'm referring to. The TV started only as only musicals on it,. But eventually proceeded up to today's oriented world, with movies, sports, and violence. Today more than 98% of all households have a TV. Over 75,000,000 of TV sets are color. To how haw our lives depend on TV; according to A.C. Nielsen, America watches more than 7 hours per day. Many people
Heat Conservation Advantages for Penguins When Huddling Aim and Introduction My aim is to find out the heat conservation advantages are for penguins are when huddling. I will be huddling boiling tubes (to represent the penguins) containing hot water (to represent the penguins' blood) and measuring the temperature over a period of time. I also had a control boiling tube on its own to see how the temperature is affected by not huddling. =====================================================================
The catastrophe that tragically affected more soldiers than any other element of the war was disease. Diseases did not only affect the soldiers in a tremendous way. As I will discuss in greater detail further in this paper, diseases gave an advantage to the Northern side of the war, and this played a role in their victory. Additionally, the treatments and discoveries that were made as diseases were treated led to spillover effects that have changed certain aspects of our lives today, providing
The Advantages and Limits of Ethnographic Reflexivity Awareness of writing choices generates an appreciation of the reflexivity of ethnographic research. Reflexivity involves the recognition that an account of reality does not simply mirror reality but rather creates or constitutes as real in the first place whatever it describes. Thus ‘the notion of reflexivity recognizes that texts do not simply and transparently report an independent order of reality. Rather, the texts themselves are implicated
Advantages of magnet schools Why would students want to attend a magnet school? The reason may be because magnet schools offer a variety of specialized programs that students can choose from. Programs such as visual and performing arts, mathematics, sciences, and many others are available for students to choose from. Similar to having a major in college, students at magnet schools have their own specialized area that they can take classes in, in addition to basic academic classes. They are encouraged
Advantages & Disadvantages of Franchising Franchising is ‘a continuing relationship in which the franchisor (the owner of a company) provides a licensed privilege to the franchisee (the buyer) to do business and offers assistance in organising, training, merchandising, marketing, and managing in return for a consideration. It is a form of business by which the franchisor of a product, service, or method obtains distribution through affiliated dealers (franchisees).’ (http://www.business.gov) A
ABSTRACT During a recent company meeting, we discussed the benefits of substituting a synthetic based motor oil for the conventional petroleum based oil now used in our new production vehicles. This report investigates the advantages and feasibility of using synthetic oils. Several oil manufacturers, as well as top engineers and engine builders, have submitted first hand information on this topic and strongly support the use of synthetic oil. The use of this product will benefit our company
the previous value, possibly exceeding the capacity of a single register(this is also how floating points are stored in some cases, as an interesting sidenote). So, now comes the ever-important question. How can we use these attributes to our advantage when writing shellcode? Well, let's think for a second, the instruction takes only one operand, therefore, since it is a very common instruction, it will generate only two bytes in our final shellcode. It multiplies whatever is passed to it by
Classes: Advantages and Disadvantages Most people have very busy lives, thus not leaving much time for anything else. Many of these people would like to have the time to return to school for different reasons (i.e. earning a higher degree, taking a class on something they enjoy, ect.). What comes to mind when trying to fit schooling into ones very busy schedule is online classes. Taking classes online has become very popular lately. Although popular, these classes have their advantages and disadvantages
