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.

The volume of a right circular cylinder is pi r2 h. The volume displaced by the 20mm piston is pi 102 200, or 62831.8. The volume displaced by the 100mm piston must be the same, so solve for h in pi 502 h = 62831.8, or h = 8mm.
What is the tensile strength of a can?
conductor that can withstand tension force before failing i.e., zebra conductor can withstand 13290 kg.
You can quote tensile strength only as [force / unit of cross-sectional area]. The above example is useful only if it a specific material (it looks like a trade-name for something) made in only one size.
Why the power required in grinding process is more than turning?
Turning uses a knife edge to shear a piece off
grinding uses a stone to abrade and break off a pieces the width of the stone
turning point or line contact
grinding area contact
What is the power source of a hovercraft?
The power source of a hovercraft is generally a battery system with an electric motor or a gas engine. The hovercraft is lifted using a large fan.
Like Hoover for vacuum cleaners, Locktite is a generic term for any liquid which is applied to the threads of nuts and bolts to prevent them coming undone in use. It is used exensively in the automotive and aviation industries. The Lockitite company also make a superglue. Loctite is a brand of adhesives, which includes acrylics, anaerobics, cyanoacrolates, epoxies, hot melts, silicones, urethanes and UV/light curing adhesives. The name Loctite was chosen in 1956 by the daughter-in-law of Vernon Krieble, inventor of an adhesive resin that hardened in the absence of air, as a replacement for less-reliable locking washers when securing bolts and screws.The Loctite brand is since 1997 part of Henkel, a German family company with interests in many chemical and industrial products.
How do you calculate the volume of a horizontal vessel?

What is the definition of the LD ratio of a screw?
What is the L/D ratio in term of screw of extruder
Why does the different layers of plywood go in different directions?
The plywood has more stiffness in one direction than it does in the other.
What are the three main functions that gears perform in a mechanical system?
Transmit rotation, power, and change "input to output" ratio's.
How do you put on landing legs on a semi step deck trailer?
They're bolt-on components. You'll need an impact wrench, and a torque wrench to ensure that you torqued the bolts properly (which is very important, given the function of the landing gear).
What are the good things and bad things about mechanical engineer?
One bad thing about mechanical energy is its very slow. But we are being green by using it because we do not use nonrenewable resources.
P.S. I know that's not the question!!!!!!!!!!!!!
How do you make a triangular screwdriver?
This question doesn't state where or why a triangular screwdriver is needed, so this may just be a "wind-up" or "troll" question.
It is is very unusual to need a screwdriver with a triangular-shaped tip!
Anyway here's how it may be possible to do it:
Grind the tip of a normal screwdriver to a point using a suitable power grinder.
Then place the shaft along a suitable heavy piece of steel - such as an off-cut of railroad rail placed upon a solid floor or a very strong workbench, or similar - and try to flatten the shaft of the screwdriver to get a triangular cross-section (with 3 long edges) by using a suitable heavy hammer.
If the shaft doesn't "take" the hammering you will first have to anneal the shaft of the screwdriver by heating it up to red heat and then let it cool in the air slowly. To be sure it gets the best chance of annealing fully, don't "quench" it by using water or an air line to try and cool it down more quickly.
Then try hammering it to the triangular shape you want. If will be very tricky to do because as soon as you hammer the opposite side to the "sharp" side of the triangular cross-section, you will find you flatten-out the sharp side! One way to avoid that happening would be to machine a V-shaped groove of suitable depth into a a piece of steel and then hammer the shaft into the groove. But, to be able make that groove, you would need to know how to use the right kind of machinery - such as a shaping machine or a milling machine - and, if you already had that kind of machinery available to you, you would not be asking this question here!
After you have hammered the shaft into a triangular cross-section - assuming you find you really can do it! - you must then harden the shaft again by heating it up to red heat and then quench it as quickly as possible by plunging it into a large bucket of cold water.
If you don't harden it properly before you try to use it as a screwdriver, the shaft will just twist around and around because it is too soft!
Good luck!
How much is a cast iron tub worth?
If the condition is decent and it is extra deep and long over $3,500
State of varying the rotational speed of machinery?
Power output will increase. Beyond the critical speed, torsional failure may occur.
What is MVW and HVW in water spray system?
MVW: Medium Velocity Water spray system
HVW: High Velocity Water spray system
When a load is applied on a fastener until it breaks the load at which it breaks is called the?
It could be called the 'point of failure.'
The main purposes of an airspeed indicator in an aircraft?
The primary purpose of an airspeed indicator in an aircraft is to give the pilot some sense of how fast the aircraft is moving. A pitot tube, which is a forward pointing hollow tube that is mounted on the plane, is pressurized by the force of the air the plane encounters as it flies. This air pressure is compared to a static reference, and the difference is proportional to the airspeed. The faster the plane moves, the higher the pressure in the pitot tube, and the greater the difference between that and the reference. All that will result in higher indicated air speed. There are some issues associated with the accuracy of the system (like when the plane is flying into a headwind), and information on that and more detail in general can be found by using the link to Wikipedia. The pictures are informative, and a reader can pick up a handful of specialized terms relating to the device and the principles upon which it operates.
Answer
The airspeed indicator provides the pilot with an indication of relative airspeed -- or how fast the aircraft is moving relative to the air in which it is flying. This is important to a pilot because it is relative airspeed that affects the performance of the airplane. If airspeed gets too low, the plane will stall; if airspeed gets too high, the plane will suffer structural damage/failure. By monitoring airspeed, and making necessary control adjustments, a pilot ensures that the airplane performs as designed. Fortunately, aircraft are designed -- and pilots are trained -- such that these extreme cases are routinely avoidable.

this is a really good website http://www.careerone.com.au/webdav/site/jobs/shared/salary_survey08/ConstructionProperty.pdf it has all the information i needed and i think it will help you. :)
Can you torque 8.8 grade steel?
Of course! Grade 8.8 fasteners are often refered to as "high tensile" fasteners where "8.8" refers to the tensile yield strength of 640MPa (UTS: 800MPa) and standard torque figure calculations apply based on bolt diameter (root diameter of thread), grade (8.8 in this case), 90% Yield strength and adjusted for surface finish and lubrication. Refer to engineering handbooks or good ol' google.
