what is a music ?

Music is an art form whose medium is sound . Common elements of music are pitch (which governs melody and harmony ), rhythm (and its associated concepts tempo , meter , and articulation ), dynamics , and the sonic qualities of timbre and texture . The word derives from Greek μουσική ( mousike ), "(art) of the Muses ." The creation, performance , significance, and even the definition of music vary according to culture and social context. Music ranges from strictly organized compositions (and their recreation in performance), through improvisational music to aleatoric forms. Music can be divided into genres and subgenres , although the dividing lines and relationships between music genres are often subtle, sometimes open to individual interpretation, and occasionally controversial. Within " the arts ," music may be classified as a performing art , a fine art , and auditory art. There is also a strong connection between music and mathematics . To many

GPS Guide to Aerial Surveillance With an ever-increasing appetite to know about people's on-the-ground activities, both foreign and domestic, the U.S. government proves an apt customer for companies developing innovative aerial surveillance platforms. Recent demonstrations launched an aerosphere resembling a gargantuan ping pong ball and ducted fan vehicles that can hover, zoom, or perch on a building ledge. These unmanned vehicles require autonomous navigation, and GPS quite naturally fills the bill. The SA-60 aerosphere can hover at 16,000 feet, observing 154 square miles beneath it. AerospheresThe U.S. Navy contracted for tests and evaluation of the SA-60 spherical airship produced by Techsphere Systems International of Atlanta, Georgia, with New Orleans, Louisiana-based Proxity Digital Networks and its subsidiary Cyber Aerospace. The SA-60 low-altitude airship can carry a customer-specified sensor suite for battlefield or homeland surveillance, monitoring warzones or other ar

Independent Suspension

Image
Independent Suspension An independent suspension is engineered so that one wheel can move up or down without affecting the motion of the other wheel on that axle. This helps improve the car's handling. Independent suspension is a broad term for any automobile suspension system that allows each wheel on the same axle to move vertically (i.e. reacting to a bump in the road) independently of each other. This is contrasted with a beam axle , live axle or deDion axle system in which the wheels are linked–movement on one side affects the wheel on the other side. Note that “independent” refers to the motion or path of movement of the wheels/suspension. It is common for the left and right sides of the suspension to be connected with anti-roll bars or other such mechanisms.  The anti-roll bar ties the left and right suspension spring rates together but does not tie their motion together. Most modern vehicles have independent front suspension (IFS). Many vehicles also have an independen

Horsepower

Image
Horsepower In technical terms, one horsepower is the energy required to lift 550 pounds 1 foot in one second. In automotive terms, it's a form of power generated by the engine. While torque is the engine's rotational force, and the energy that gets the car moving from a stop, horsepower is the energy that helps the car keep accelerating when it is already moving.

Governor

Image
Governor The governor is a safety device in most modern cars. It regulates the car's speed by mechanically preventing the car from going over a certain speed. So, though a car may be mechanically capable of going 180 miles per hour, the governor can be set to limit its speed to 120 miles per hour. Once a diesel engine is running, the engine speed is monitored and controlled through a governor.  The governor ensures that the engine speed stays high enough to idle at the right speed and that the engine speed will not rise too high when full power is demanded.  The governor is a simple mechanical device which first appeared on steam engines.  It operates on a diesel engine as shown in the diagram below. The governor consists of a rotating shaft, which is driven by the diesel engine.  A pair of flyweights are linked to the shaft and they rotate as it rotates.  The centrifugal force caused by the rotation causes the weights to be thrown outwards as the speed of the shaft rises.  If the

Flywheel

Image
Flywheel A flywheel is a heavy wheel, where energy is stored as momentum. In cars, the flywheel sits between the engine and the transmission. It spins, storing energy from the engine. When the transmission engages the flywheel, that energy is transferred.

Engine

Image
Engine The engine takes up most of the space under a car's hood and provides power to the entire automobile. It does this through internal combustion. The engine takes fuel, like gasoline, adds air and a spark, to create a series of small explosions. Those explosions move components inside the engine, which in turn power other components that make the car move

Drivetrain

Image
Drivetrain A car's drivetrain includes all parts that make or send power to the wheels. For most cars, the drivetrain refers to the engine, transmission, driveshaft, differentials and drive wheels.

Differential

Image
Differential A differential is part of a transmissions gear system. It allows one wheel to turn faster than the other Car Differential is a small device that helps in splitting the torque of your car’s engine in such a manner, which will allow the wheels to move at different speed. These differentials play an important role while turning of the car. Car differential is a small device, which splits your car engine’s torque in two ways and allows each output to have a spin in different speed. Car differential is found in all modern cars . Differentials are also found in most trucks and all-wheel drive vehicles. All-wheel drive vehicles require a differential between each of their drive wheels set. They also require one in between the front & back wheels too, as the front wheel travels different distances while turning than what is travelled by the rear wheels. Part-time 4-wheel drive systems do not have car differentials between their front & rear wheels. Instead , what you’ll

Cylinder

Image
Cylinder On an internal combustion engine, a cylinder is the space in which the combustion takes place. It also houses the piston and connecting rod. By looking at an engine's cylinder block, you can tell what kind of engine the car has. If the cylinders are in a straight line, it's an inline engine. If there are two rows of cylinders facing each other at an angle, it's a V engine. It the cylinders are in two rows, but lying flat across from each other, it's a horizontally opposed or boxer engine. The number of cylinders, as well as their layout, tells you if the engine is an inline four, V8 or another type. Cylinders are also sometimes called bores

Crankshaft

Image
Crankshaft The crankshaft is a rod that is connected to the pistons in an engine. As the pistons move up and down due to combustion, they rotate the crankshaft. This rotational force travels down a car's drivetrain and eventually powers the car.

Clutch

Image
Clutch A clutch connects and disconnects the transmission from the engine, allowing the flow of energy to momentarily stop so the transmissions gears can be changed. In an automatic transmission, this happens without driver input. In a manual transmission, the clutch must be disengaged before the driver changes or selects a gear

Carburetor

Image
Carburetor In older cars and some motorcycles, the carburetor mixes the correct amount of air with fuel to create internal combustion. In modern cars, this is done automatically by the fuel injection system.

Body-on-Frame

Image
Body-on-Frame In this type of car design, the car's body is a separate unit from its chassis or frame. This is a common form of construction for older cars, as well as modern trucks and some SUVs. Most modern cars use unibody construction

Automatic Transmission

Image
Automatic Transmission An automatic transmission routes the engine's power to the wheels with little input from the driver. It selects gears and changes them at an appropriate time based on set parameters. This is the most common type of automotive transmission in the United States.

Alternator

Image
Alternator The alternator is what keeps a car's battery charged. In essence, the alternator is a generator run by the car's engine. Most alternators are attached to the engine by a belt. As the engine runs, it spins the belt, which turns components in the alternator that change this mechanical energy into electrical energy. That electrical energy is stored in the battery. Keep your alternator running smoothly by routinely checking the belts that connect it to the engine. Make sure the belts aren't dry or frayed, and are tightly connected to both the alternator and the engine.

Air/Fuel Mixture

Image
Air/Fuel Mixture Also it is called the air/fuel ratio, the air/fuel mixture is ratio of air to fuel present in an engine during combustion. The correct air/fuel mixture will result in good engine power and efficiency. The wrong mixture will result in suboptimal performance and efficiency. On older engines, this mixture is made in the carburetor. On newer engines, the fuel injection system injects the correct amount of fuel directly into the cylinder for the best combustion .

Hybrids on the Construction Site

Image
When you drive down the street, you see hybrid automobiles every day. But how about a hybrid bulldozer? We'll talk about hybrids on the construction site, today, on Engineering Works! Or listen to the podcast . Hybrid automobiles have been around for quite a while. Honda introduced the first gasoline-electric hybrid to the United States in 1999. In 2004, Toyota started selling the Prius and Ford’s Escape hybrid S-U-V came on the market. Now, it seems like everybody’s got a hybrid. Even Cadillac and Mercedes-Benz. Everybody sees why driving a hybrid makes sense, mostly great gas mileage. Some, more than 50 miles per gallon. And then there’s the hybrid bulldozer. Yep, bulldozer. You know, the big yellow machines that push dirt around construction sites. Caterpillar has brought out a hybrid bulldozer, a diesel-electric version of its D7 dozer. It’s the first one, and it seems to do the same for dozers that the Prius and its automotive brethren do for automobiles. The D7E, for electric

four-bar linkage

Image
A four-bar linkage [or] simply a 4-bar or four-bar is the simplest movable linkage . It consists of four rigid bodies (called bars or links), each attached to two others by single joints or pivots to form a closed loop. Four-bars are simple mechanisms common in mechanical engineering machine design and fall under the study of kinematics . If each joint has one rotational degree of freedom (i.e., it is a pivot), then the mechanism is usually planar , and the 4-bar is determinate if the positions of any two bodies are known (although there may be two solutions). One body typically does not move (called the ground link , fixed link , or the frame ), so the position of only one other body is needed to find all positions. The two links connected to the ground link are called grounded links . The remaining link, not directly connected to the ground link, is called the coupler link . In terms of mechanical action, one of the grounded links is selected to be the input link , i.e., th

Turbine-Powered Car Accelerates Like a Jet

Image
THE GIST OF THE STORY Jaguar has unveiled a new turbine-powered car, the C-X75. The car runs on micro-sized turbine engines that burn fuel to charge the battery, which powers four electric motors. The car can go from 0-62 mph in 3.4 seconds and has a range of 560 miles.   ===========================================================   Jaguar, working with Bladon Jets, recently unveiled a hybrid concept car, the C-X75, that can accelerate from 0 to 62 mph in a blistering 3.4 seconds. The car gets its power from two new micro-sized gas turbine engines that are slightly larger and longer than a human forearm. The jet-like engines feed four electric motors, which give the car a range of 560 miles. "It has long been a dream to get gas turbines into a car; the automotive industry has been trying for 50-plus years," said Gary Lamb, Director at Bladon Jets. "It is only now that we have a viable proposition." To most people a gas turbine engine is the huge c

Hypersonic 'WaveRider' Poised for Test Flight

Image
April 29, 2009 -- Hoping to bridge the gap between airplanes and rocketships , the U.S. military is preparing to test an experimental aircraft that can fly more than six times faster than the speed of sound on ordinary jet fuel. the X-51, but folks like to call it the WaveRider because it stays airborne, in part, with lift generated by the shock waves of its own flight. The design stems from the goal of the program -- to demonstrate an air-breathing, hypersonic, combustion ramjet engine, known as a scramjet. "We built a vehicle around an engine," said Joseph Vogel, the X-51 project manager with Boeing, which is building a series of four test planes under a $246.5-million program managed by the Air Force Research Laboratory in Dayton, Ohio. Scramjets use the forward motion of an engine to compress air for fuel combustion. It's similar to a ramjet engine, but at supersonic speeds. NASA tested the concept in 2004, breaking the record for a jet-powered aircraft

New Solar Power From Old Technology

Image
New Solar Technology To Generate Electricity is almost a cliche these days. Let’s look at some promising old technology. Today, on Engineering Works! Listen to the podcast. When people talk about solar energy, they usually mean one of two things. Photovoltaic panels or solar concentrating plants. Some engineers are trying something else. An updated version of a two-hundred-year-old invention to turn sunlight into electricity. This old technology is something called a Stirling engine. A Scottish clergyman named, you guessed it, Stirling, invented it in 1816. The idea is simple. A Stirling engine has two cylinders and pistons. Kind of like a two-cylinder motorcycle engine. The space above the pistons is filled with a fluid, usually air or helium. Heat the gas in one cylinder and it expands, moving the piston. The gas cools and moves to the other cylinder, where it moves that piston and flows back to the first cylinder, where it’s heated again and the whole cycle starts over. It’s m

New Look to an Old Engine

THE GIST OF THE STORY Combustion engines are incredibly inefficient. Some engineers are looking into ways to recover wasted energy. ================================================================   To hear some people tell it, the internal combustion engine is dead. Some engineers aren’t so sure. We’ll check it out. Today, on Engineering Works! Listen to the podast. Just about everybody knows a little about internal combustion engines. They’re what powers almost all of our cars, trucks and motorcycles. They’ve been around for more than a hundred years, and they’re boring. They’re also really inefficient. Only about a quarter of the energy in fuel actually turns the wheels and takes us down the highway. The rest, mostly heat, is just wasted. Engineers are looking into some nifty ways to get that wasted energy back. One group of British engineers are working on a tiny turbine that would fit in the tailpipe. Exhaust from the engine would spin the turbine. It would drive

Airplanes in Space?

Image
GIST OF THE STORY ================================================================== A British company is working on a spaceplane that can carry cargo or a pod for passengers to orbit. A critical piece of technology for the spaceplane's engines is currently under development. The spaceplane could ferry cargo and passengers into space more cheaply than current alternatives ============================================================   A British firm is upping the ante in a long-held dream to build an airplane that also can fly in space. With support from the U.K. Space Agency, Reaction Engines is building a prototype of a critical piece of its spaceplane's technology, which will be tested on a conventional jet engine. The ultimate goal is Skylon, an unpiloted, air-breathing vehicle that takes off and lands on a runway, and can travel beyond Earth's atmosphere. Rather than using expensive rocket motors that have to be discarded or refurbished after every flight

THE GIST OF THE STORY ------------------------------------------------------------------------------------------------------------ A new kind of fuel cell runs on diesel instead of hydrogen. A fist-sized fuel cell produces 250 watts of electricity, enough to power yachts and mobile homes. ------------------------------------------------------------------------------------------------------------   Diesel, a fuel once derided as being too loud and too dirty, could be the key to clean, quiet and more environmentally friendly energy. A Norwegian company, Nordic Power Systems, in conjunction with Cal Tech spin-off SAFCell Inc., recently released a new fist-sized, diesel-powered fuel cell that produces 250 watts of electricity, enough to power yachts or mobile homes. Scaled up, the researchers could use the fuel cells to power even more energy-hungry machines. "Diesel is available most places, is not seen as a hazardous fuel in any way, has high power density, and (our
