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 the tachometer princibal?
THERE ARE TWO TYPES OF TACHOMETER. 1.D.C. TACHOMETER 2.A.C. TACHOMETER ALSO DIGITAL TACHOMETERS CAN BE CONSTRUCTED using various principles..... D.C. TACHOMETER its construction is very similar to a D.c. generator. it works on the principle of generation of emf wen a rotating conductor cuts the magnetic flux......when magnetic flux is constant then the emf produce is directly proportional to the speed of the armature that is coupled to the shaft of motor. A.C. tachometer its construction is similar to a two phase servo motor.... and works conversly of it....
Mechanism of tiptronic gear transmission?
The mechanism of the tiptronic gear transmission is rotation. The tiptronic gears are usually an automatic transmission that allows the driver to control the gears like it is done in a manual transmission.
How are synchros used in error detection?
Control systems are synchros which are used in error detection. They provide a voltage to be converted to torque through an amplifying method.
Difference between compressor and pump rotor?
The only one difference in b/w compressor and pump rotor is impeller shroud width.Fluid is incompressible so impeller shroud width is not change and gas is compressible so impellers are tends to thin in width to the discharge side.
What is a French Curve used for?
It is used for mechanical drawing of curves and has applications in such things as weather maps, etc. unlike slide rules they are still currently manufactured by among others, Ko-Hi-Noor of Paris. they have various engineering applications, as stated,
What rockwell c hardness is grade 10.9?
The Rockwell C Hardness for a grade 10.9 fastener is 32 - 39HRC or 320 - 380Hv10
Steel handsaw, steel hacksaw and steel bandsaw blades are made from high speed steel. The most popular specification of steel used to produce these products is BS4659 BM2 commonly known as M2 high speed steel. M2 offers good wear resistance with excellent toughness after heat treatment.
Find the resultant velocity if x and y components are given?
Resultant is equal to the square root of the sum of the summation of x-components and the summation of y-components
What is the difference between API 6A and API 6D valves?
It's quite easy. API 6A speaks about wellhead and x-mas tree equipment, API 6D speaks about pipeline valves. If you are phisically looking to one valve, you can also understand if it belows to 6A or 6D giving a look to the valve label. On the label you can read the class of the valve. If the class is 2000 or 3000 or 5000 or 10000 or 15000 or 20000 the valve is 6A. If the class is 125 or 150 or 300 or 400 or 600 or 900 or 1500 or 2500 the valve probably is a 6D ("probably" because the same classes of API 6D are used also by other API standards, like 594, 600, 608, ecc ecc).
How do I create a vacuum from an air flow?
By forcing the air through a narrow opening you get a lower pressure zone just behind the restriction.
What is the maximum span on a double 2x12 beam supporting a 2nd floor load with no roof load?
About 5metres(16') but would have to be stress graded timber.
A weld is the fusing of materials by melting. Metals, glass, and some plastics can be welded. Not to be confused with brazing, soldering, or glueing.
Yes, when designing something out of wood, it is very important to think about what it will be used for. You would want to make sure that it will hold up and do whatever job it is suppose to do.
What is mechatronic engineering?
Mechatronics engineering is the design and creation of computer controlled electro-mechanical systems. :) In other words...
'robotics... and a bit more.
A Weldolet is a butt-weld branch connection. It is designed to provide integral reinforcement and minimize stress. They are made to match or exceed the schedule of the pipe.
