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 types of welding used in car?
From the factory a lot of SPOT WELDS are used. That I know. Whenever you see a bunch of circles in line, spaced out, and at the joints of two surfaces-thats a spot weld.
For doing "re-word" or modifying, typically MIG is used for many applications. However, others can be used as well.
What cf8m material stands for?
It is a casting of 316 stainless, with higher values of Nickel, Chromium, and Silicon.
What are automated machine tools known as?
Automated machine tools are more commonly known as numerically controlled (NC) machine tools.
Each metal when placed into an electrolyte, water, seawater, soil or any other good electrolyte, has an electric potential. This potential is different for every metal.
The galvanic series is a list of this potential arranged from the most "active",lower potential to the most "noble", higher potential.
The terms "noble" and "active" means that when two metal are connected the most "active", with the lower potential will corrode, while the metal with the higher potential, the "noble" material will not corrode.
The galvanic series, the potentials, are different in different electrolyte.

What are parts of a washing machine and their functions?
There r diff parts in washing machine. First thing is the sensor used in it to made it automatic. Next comes the washing drum,where in cloths r washed. next is the inlet/outlet for the water flow......
What are the different types of spring loaded centrifugal governors?
mainly three types of spring loaded centrifugal governors
It is popularly thought that John Dunlop, a Scot, invented the pneumatic tyre. However, another Scot by the name of Robert William Thomson from Stonehaven invented the pneumatic tyre some 43 years earlier.
A noteand a fuller answer
This question isn't only asking about the inventor(s) of pneumatic tires! It just asks about "tires". The answer is that, long before pneumatic tires were invented, solid tires made of wood or iron were fitted to stone, wooden or metal wheels to make them last longer.
The reason for fitting such tyres is that, if you don't have a separate tire, when its outside edges get chipped and worn away, the whole wheel - or maybe at least its rim - has to be replaced.
So it is probable that tires were invented soon after wheels, because the people who invented wheels soon found out it was a good idea to have tires on them simply because because they can be replaced more easily when they get damaged or wear away.
What turbine does not require draft tube?
Draft tube is used to increase the pressure from the low turbine exit pressure to the pressure of the surrounding to which the fluid is rejected.
Only reaction turbines require a draft tube as there is low pressure at the exit of the turbine,where as in an impulse turbine the pressure at the inlet and the exit is essentially the same, which is above the pressure to which the fluid is rejected and thus it require no draft tube.
What does a centrifugal compressor do?
Centrifugal compressor sucks in air, compresses it and ejects it, decreasing surface area without losing pressure, propelling an object forward. These devices power jet aircraft.
How much wood is required to generate 1 ton of steam?
Near to 400 pounds.
One pound of steam requires the input of 1080 btus of heat added to 32oF water at atmospheric pressure. One ton or 2000 pounds requires the input of 2.16 million btus, and a boiler with 80% efficiency (common value) will need 2.7 million btus of heat from the combustion of the wood. Assuming the wood has a btu heat content of 6500 btu/lb (commonly most woods are 6000 to 7000 btu/lb) then about 415 pounds of wood are required to produce 1 ton of steam. In practice only 375 pounds of wood are needed to maintain a steady output of one ton of steam in a boiler, as the water when reintroduced into the boiler is very close to the steaming temperature and doesn't need to be heated from 32oF.
What came first petrol engine or diesel engine?
The gasoline engine came first. The gasoline engine was invented and patented in 1823 with the first efficient gasoline engine developed in 1876. The diesel was invented in 1893 which was 70 years after the gasoline engine.
How many people can you fit in a 20 foot container?
It is illegal to smuggle human beings, so the answer to this is none.
Goldfish. They get in at night, have underwater cocktail parties and leave the ice floating about.
An electric start for a 49cc pocket bike?
All it does is start the bike with a flip of a switch and the oush of a button. Instead of pulling the rope a billion times.

State how the size of a center lathe is specified?
the size of a lathe can be described by either of the following ways.
1.DISTANCE BETWEEN THE TWO SPINDLES.
2.SWING DIAMETER.ITS THE DISTANCE MEASURED FROM THE SADDLE/CARRIAGE TO THE CENTRE OF THE SPINDLE.
The EPR valve should work reguardless of if the TXV is in the air stream. The TXV in the airflow shouldn't make it act any different since it is sensing the temperature at the bulb instead of at the valve it's self.
Why do cars burst into flames on impact?
Cars can burst into flames on impact due to the release of flammable fluids, such as gasoline or engine oil, ignited by heat from the collision. The impact can rupture fuel lines or damage the fuel tank, leading to a dangerous combination of fuel vapors and heat. Additionally, the electrical system of the car can be compromised in a way that causes a short circuit and sparks that ignite the flammable substances.
A control system that appears to be self-regulating. Closed-loop systems employ feedback and a reference of correctness (norm or set point). Deviations from the norm are detected and corrections made in order to maintain a desired state in the system. Closed loop systems provide the homeostatic mechanism of many physiological functions (see negative-feedback) and also control some movement patterns, where feedback from proprioceptors and other receptors play an important part. Compare open-loop-system.
What is the working principle of worm gears in sand mullers?
Sand mullers break up sand after it has been used in molds to facilitate sandcasting. By effectively breaking up the sand, it can be reused. The worm on a motor or on the "driven" side of the device will engage with a worm gear. The worm rotates continuously, and the spiral cut gears "worm" their way "along" the axis of the gear. The worm gear (or spur gear) engages with the worm and rotates continuously as well. Also, the worm gear will translate the rotary motion of the worm by 90 degrees. It is fairly easy to see how the unit works if you look at some pictures or drawings. Hey, how about some animation or video? Got a couple of links.
