Mechanical Engineering
Mechanical Engineering is a branch of engineering that encompasses the generation and application of heat and mechanical power and the design, production, and use of machines and tools. Mechanical engineering involves application of the principles of dynamics, control, thermodynamics and heat transfer, fluid mechanics, strength of materials, materials science, electronics, and mathematics.

What is scavenging process in an engine?
compressed air is sent to the combustion cylinder with the help of blowers etc.,it helps to clean the cylinder of burnt gases, this process is known as scavenging.
Can y strainer and a butterfly valve be assembled flange to flange?
No, U cnnot accomodate it without pipe sppol, because of isolation.
Is the heat treatment of polymers possible?
Yes but it has very different effects than heat treating a metal.
When plastics are molded a certain amount of what is called molded in stress is applied when the part is cooled. The amount of molded in stress depends on the shape of the part cooling time etc. To reduce molded in stress generally you would increase the mold temperature and increase cooling time. However that gives us longer cycle times which costs money. With that said...
Heat treating plastics will help get rid of molded in stresses however will normally cause part warppage. On the other hand when done at lower temperatures heat treating a plastic for a short period of time prepares a plastic surface to be painted.
Heat treating a plastic for painting changes the surface energy of the material making it easier to apply the paint and produces a better adhesion.
An ordinary compass is a --- box with a needle inside it?
It generally a round device, something like a small covered dish, with a small post in the center with a magnetized needle attached in such a way that it can turn freely. The dish is usually filled with air, but it is not uncommon for it to be filled with water, either.
Could a bad axle make a loud roaring noise?
most likely it is your rear end . axles when they go bad either wabble or brake
How are horsepower and thrust related in a jet aircraft?
The more horsepower you have, the more thrust you will be able to produce. The more horsepower you have, the more thrust you will be able to produce.
Why was the Eiffel Tower biult?
As an entrance to the Paris World Exhibition, completed in 1889, built in two years by 50 engineers and 132 workers
How difficult is a mechanical engineering degree?
Depends on how difficult you find Physics and Calculus.
What year did Franklin make the 6152 sewing machine?
Franklin, Ben that is, invented Bifocal glasses, a Lightning rod ( or arrestor) and the Franklin stove, a type of fireplace. he also devised the Franklin long arm lever grip device used well into recent times in Grocery stores. Franklin did not invent or design, market, etc Sewing machines. Elias Howe, and Isaac Singer (sewed-up) that trade!I have never heard of a Franklin sewing machine- White, yes, Singer, Necchi, Pfaff or something like that, even Egyptian models, but no Franklins.
How does altitude affect a Surface to Air missile range?
Gravity is pulling the projectile down steadily; the further it climbs, the more resistance it's recieving, it begins to slow down, as with any projectile.
What is the thermal expansion coefficient for monel?
Thermal expanasion coefficient fro monel is 0,0000075 m/mºC. More info at http://www.engineeringtoolbox.com/linear-expansion-coefficients-d_95.html
The engines used by the aircraft produces thrust and also motion to the aircraft in order to give speed to the aircraft so that the wings can produce lift that is greater than what actually the areoplane weighs with its cargo, passenger and the fuel on board. The amount of lift should be greater the the aircraft's mass so that it can stay in the air.
The aeroplane has an aerodynamicaly shaped (streamlined - to reduce drag or air friction ) body, with it's wings stretching out as much as 211ft (Boeing 747). Generally, such a large wingspan is to have a large surface area to give the plane a lift of the ground. Now, the huge winged turbones placed beneath the wings when started pushes the aeroplane forward from 0 to as much as 932 miles per hour during take off period and then cruise of at 300+ milse per hour at such speeds this creates a pressure difference on the belly side of the plane and the upper surface. The upper surface creates a low pressure and the belly side creates a high pressure so the wind tends to move from high pressure to low pressure area. Thereby giving the plane enough lift for initial take off. Similar pressure difference exsists when the plane is in motion as well which maitains the flight in its path. When sudden pressure differences occur in air ( generally reffered to as turbulence) causes the flight to shake or jerk when in air. hope this answers your questions

Benjamin britten's famous works?
He was famous for riding motorcycles, his Britten V1000 in fact, he was also famous for building the Britten V1000 with limited equipment in his back yard
- Born 1 August 1950 in Christchurch.
- Trained in mechanical engineering, and worked as a design engineer.
- Established own business making stained glass and lights.
- Married Kirsteen Price and had three children - Sam, Isabelle and Jessica.
- Began designing motorcycles and developed the Britten V1000 using his own design and construction techniques to make a faster, lighter "superbike".
- After years of mixed success Andrew Stroud won the world individual BEARS championship in 1995 riding a Britten bike.
- Died on 5 September 1995 from a malignant melanoma.

Why were bridges and tunnels important to rail roads?
Due to the weights of the vehicles and the low coefficient of friction between a smooth steel rail and wheel, railroads are limited in the sharpness of curves they can follow and the amount of grade, or slope, they can climb.
What is abs injection molding?
is a manufacturing process for forming objects, as of plastic or metal, by heating the molding material to a fluid state and injecting it into a mold.
Can steam coming from your car engine mean you are low on oil?
if it's coming from the tail pipe or an exhaust leak, it means you have a blown head gasket!
What would happen if you connect large sewer pressure pipe to a small pressure pipe?
Nothing as long as the pressure pipe is not used for potable water as you cannot make a direct connection and depending on the GPM flow what size the larger sewer pipe is as 1 GPM (pumping) is considered 1 fixture unit when sizing the drainage system ALSO make sure the pumps system enters at a right angle 45 deg so your not eroding the side of the larger pipe out
Some silver chains are mad by hand with individual wire links that are formed, linked and soldered together. However, most silver chains are machine made by a series of operations. First wire is drawn to the proper thickness or gauge and annealed for workability. It is then fed into various types of machines that form links of certain shapes in a pattern and connect them together. Finally, a soldering operation fuses the links together so they are secure. Chain is made in continuous lengths on spools. Later, different machines will cut chain to specific lengths and connect the jump rings and clasps to create finished necklaces. There are many differend chain styles. The reference link below provides more details.
I have a 1993 Dodge D350 cummins diesel engine how can I get more power out of it?
bigger turbo, injectors
you can also put an HP chip in it
sorry this guy is incorrect with the chip answer dodge has a mechanical fuel pump till 1998 so if you know a good diesel mech you can have them turn your stock pump up to get more power.
but before you do any thing get a K&N air filter and put a straight pipe on it. these two will help and you should get better fuel milage
if that's not good then injectors and a turbo
