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 upstream and downstream system?
Upstream and downstream systems are business terms that apply to the production process. The search for and extraction of raw materials refers to upstream. When these materials are processed refers to the downstream.
Where can you download shader modell 2.0?
im sorry but youll have to update your graphics card. PC world is a good place to start
What is rotating concentric cylinder viscometer?
Why do you use stainless steel screws on a cedar fence?
Stainless steel does not corrode like other metals do. because of the tannic acid in cedar and the fact that it will be outdoors stainless steel will resist corrision much better.
product lifecycle management or project lifecycle management, the former is most common.
What comercail aircraft has the longest range?
Boeing 777-200LR. It can fly from Hong Kong to London without refueling!
Fill out the table by describing each of the economic systems listed?
There is insufficient information in the question to answer it. There is no table. Please restate the question.
What are the differences between open die forging and close die forging?
-Open Die Forging is taking hot steel and shaping it with "flat" dies (sometimes angled; sometimes used for making "steel wheels".) Open die forging is mainly used to elongate steel.
-Closed Die Forging is taking hot steel and shaping it with impression specific dies such as tie rods, crank shafts, and yokes.
-In some cases parts need to be open forged, then closed forged.
We are a Chinese drop forging company for various closed die forging parts,check our website dropforging.net and contact us while there is any inquiry!
Is 25000 secant modulus better or worse than 120000 secant modulus?
that depends; if you are worried about deflection under load the higher the better to reduce deflection; but if you are worried about stress under temperature or constant input deflection, the lower the better.
Which types of pipe are commonly used staircase handrail seamless or nonseamless?
Seamless pipe is very expensive, and is only used in certain applications, such as steam condensate return, where ERW (seamed) pipe would not last as long. For a handrail, go with the ERW.
When do you use solid pattern for casting?
solid pattern is used to create the mould cavity. it is a full size model of a part that makes an impression in the sand.
Abnormal means NOT NORMAL i.e. the combustion which is going on with insufficient air flow producing major quantity of unburnt fuel with carbon mono oxide in the flue gases .
What is the white trail behind a ship?
It is called the wake. It is caused by the forward movement of the ship parting the water and the churning propellers aerating the water into a foam.
Yes... not your mass though. Know the difference between mass and weight. The acceleration of Gravity is less as you get further away from the center of the earth. Which would cause you to weigh less. The equation for the force of gravity is GMm/(R^2). Where G is the universal Gravity Constant wich is something like 6.67x10^(-11) and M is the mass of the earth, and m is the mass of the weight being measured. R is the distance from the center of the earth... which increases as you increase in altitude.
What does the term undercut in machining parts?
If you were t take the top surface of a part and extrude down to the XY plane. Then take the previous part and subtract it from the model you just made, those are all the undercuts.
Type of pulley that has additional numbers of ropes that help to increase mechanical advantage?
Fixed Pulley!!
Butt weld is a type of joint for welding.At this type,the connection area is put in front of each other.Another method of connection is "Socket weld"in which two parts are male and female,one goes into the other then welding operation is done.
steel is found in most part of the world as it is increasingly produced and used in all if not most parts of the world it does not occur naturally as it is an alloy of iron and other element such as carbon , nmanganese etc . also the steel is produced in steel mill.
Is there is any Indian Council for Engineering and Technical Studies in India?
yes
National Institute of Engineering, Mumbai
What is end cutting edge angle in single point cutting tool?
It is the angle between face of the tool and a plane perpendicular to the side of the shank.It varies from 5 to 15 degrees.
The main test for aluminum is by using a magnet. Aluminum is not magnetic. If a steel is tested and the magnet clings to it then that is a good indication that it is not aluminum.
What is the balance piston used for a centrifugal compressor?
Due to the pressure rise developed through the impeller, a pressure difference exists across the hubs and covers such that the impellers have a net thrust in the direction of the compressor inlet. The balance piston counteracts that by being located behind the last impeller. This is accomplished by subjecting the outboard side of the balance piston to a low pressure from the inlet side of the compressor thereby creating a pressure differential opposite to the direction of the impellers. This pressure is acheived by connecting the area behind the piston to the inlet using a line. The impeller thrust not balanced by the balace piston is absorbed by the thrust bearings.
I hope this helps
