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 happens to metal once it has been mined or smelted?
I had to answer this for homework, this question didn't help me as there was not any answers but I found something on the cycle of metal...
INGREDIENTS
Metal is a material that is mined from earth. There are many different types of metals. Many of the metals that get thrown in the garbage are scrap metal. Scarp metal is metal we don't want any more like old cars or construction waste. Metal is not biodegradable. But, it can be recycled to make many other useful products.
HISTORY
People have used metals from the beginning of times. They even named whole period of history after metals like Copper Age. Since then people have been using metal for many purpose from construction to packaging and car parts. Metals are still mined today. scientists have also found many ways to improve metals so that they can be stronger and have more uses.
USE
Metal is used everyday life everywhere you can think of for example construction workers use them to build houses and buildings, are also in computers and even in your house that you live in.Metal is and important part of buildings just think about it if your house or any building did not have any metal during a hurricane your house would very unstable and would collapse.That is why metal is such an important part of the world to have.Anywhere you look there are probably at least and inch of metal.
LIFE CYCLE
Many types of metal are recyclable and here are a few steel,tin cans,aluminum cans,empty aerosol cans,and aluminum foil plates.After metal is mined it is smelted and processed into many of the products listed above.But do you know what happens to it after it has been used?Well first you have to wash it and it would do the workers at the recycling place good if you crushed them but most people just rinse it and throw it into a recycling bin.After it has been recycled the process starts from the beginning.

What is the average piston speed at 15000RPM?
Depends on the length of stroke of the piston. A piston goes up and down once per rev. so do the the calculation how many time the piston travels up and down in a min then work it against the distance travelled.
What is the current scrap price for brass in il?
It is between .35 to .45 per ounce. It will depend on the amount of brass in the item and what item you have.
Planes can crash due to a number of reasons including pilot error, electrical/mechanical failure, bad weather, air traffic controller error, and on rarer occasions, terrorism and pilot suicide.
Accelerator Position Sensor. This measures the position of the gas pedal and is used by the ECM along with the Throttle Positon Sensor to control how much fuel is delivered to the injectors, along with a couple of other things of course.
In 1872, the "St.E.G" factories in Resita manufactured for the European railways: 16 crane travelling on rails, 18 water tower tanks, 110 plates for the return of the railway engine, 514 switch double crossing frogs, 793 cushions.
What is a Tempil stick temperature measuring crayon?
These are temperature sensitive chemicals shaped in the form of sticks.
These are not temperature measuring but temperature Indicating crayons.
You have to interpret temperature by observing the physical change taking place
form solid to liquid.
A surface is heated & you start marking (or rather touching) at intervals.for example
you have a stick of 150oc with you.as soon as surface attains 150oc you will get
liquid droplets in place of dry chalky mark.

What is the meaning of jairo in marine industry?
jairo means Bright Son in the bible; I have a cousin named Jairo and this is how I know; probably, this is posted as a joke, since this name is not common at all; and this would sound like the Japanese name Hiro, which is the closest answer you can get when looking it up in a dictionary.
What is No-spin differential axle?
The NoSpin differential is a type of differential designed by TracTech, and now owned by Eaton. It permits all the available torque to be delivered to the wheels while still allowing for wheel speed differentiation. Rather than having two side gears and one or more pinion gears (like a standard open differential), it contains a clutch on either side of the spider which mecanically engage with the spider. When one wheel is forced to travel faster than the other (such as the left wheel in a right-hand turn), the clutch on that side of the spider will disengage, allowing that wheel to spin faster. The other wheel will be given 100% of the available torque from the driveline. When both wheels return to spinning the same speed, the clutch engages with the spider again, and the differential basically acts as a locked diff. These differentials are normally used on off road machinery since the engagement and disengagement of the clutches is loud and can be felt through the driveline. They would be very annoying in high traction conditions (pavement).
