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 material to use to make homemade clock?
A clock that is easy to get the materials have tons clocks, tiny solar panels the cheap ones? (Like those key-chains that run on solar energy.) A clock can be made out of simple materials that most households already have? (Aluminum foil, etc.
Why is is high carbon steel is limited to cutting tools?
Higher contents of carbon make the steel harder but more brittle. The harder steel will cut better and hold an edge longer but has much less shear strength.
How cold and hot shortness is controlled in steel?
In steel production, shortness refers to the ability of the material to deform under stress without cracking. Cold shortness is controlled by limiting the sulfur content, as high sulfur levels can lead to brittleness at low temperatures. Hot shortness, on the other hand, is managed by controlling phosphorus levels, which can adversely affect ductility and toughness at elevated temperatures. Proper alloying and heat treatment processes also play crucial roles in mitigating both types of shortness.
It's a grade B steel alloy , used for tool making i believe.
How important measurements in mechanical engineering?
its very much important in mech enggg. even measurements lab are provided in 8th sem. but considering as an engg inspection is our least concernd
How to recover Windows 7 from recovery drive after installing a clean Windows7 from CD?
If you've reset it, do a windows backup in control panel. Make sure the files in the recover drive are not affected by the restore.
What is the difference between 304 and 304L filler wire?
304 and 304L are stainless steel electrodes.
but in 304L, L denotes Lower percentage of Carbon content.It improves the corrosion resistance character of filler wire.
A moment, M, is a rotational force measured in inch pounds; a couple is two forces, P, acting in opposite directions and separated by a distance, d. The product Pd is the couple and is measured in inch -pounds, and is an equivalent moment.
What method can be used to increase the rate of delivery of a rotary gear type pump?
increase the rpm
What is the reasons of Reciprocating compressors failure?
their are many reasons a compressor can fail (refrigeration)
1 low oil level due to low suction pressures or oil wash out due to liquid flooding back to the compressor 2 wrong supper heat setting on tx valve system3 wrong size compressor for the load 4 under or over voltage5bad starting or running cap or start relay and the list goes on....
What are difference between coc and aoc pipes?
AOC is Accidently Oil Contaminated and COC is Continuously Oil Contaminated.
How do you calculate pipe schedule?
Formula For Schedule Calculation.
1000xP/S= Schedule Number
where
P=Internal Pressure
S= Ultimate Tensile Strength
(From ilyas,Hyd)

Why isothermal transformation diagram have C shape?
I think that after heating within the first rang of temperature the crystalline structure dislocation happen and the gaps between the atoms increases more than the solid state. So that it will take time at first to reach this state then after this state is approached the time required to increase the temperature of the metal is less, but after certain time the metal reaches a liquid state. Consequently it will need to evaporate at the next phase so the temperature is settled down on a constant value because this phase needs a huge amount of energy to happen.
I wish that will be beneficial. :D:D
A pump produces movement in the fluid it is pumping. It does this by creating:
- a low pressure zone into which the fluid is drawn (vacuum pump)
- a high pressure zone which the fluid wants to escape from (tire pump)
- A physical displacement of the fluid (gear pump, worm pump)
- centrifugal forces which move the fluid outwards from its center
What is the equivalent of aisi 1026?
AISI 1026 is a low-carbon steel grade known for its good machinability and weldability. Its equivalent in the international standards is often considered to be EN 10277-2 (C22E) in Europe, or JIS S45C in Japan. Additionally, it can be compared to ASTM A108 Grade 1026 in the United States. These equivalents share similar chemical compositions and mechanical properties.
Which is stronger solid steel or Antimanium?
There is no such thing as antimanium. If you are thinking of the mis-spelling of the material using in X-Men, Wolverine, adamantium, that is science fiction. If you are thinking of antimonium, that is softer than steel.
Why are noise barriers on the sides of highways seemingly always staggered?
So you don't form a resonant chamber, a rectangle, that would cause the noise to be worse. (No, lets be reasonable, shall we?)
Another, more likely, explanation is that you need the ends to overlap, and staggering them is the only logical way to do that. (More rational, actually, don't you think?) Staggering the ends would also strengthen the "box" made up by each unit, so it would not "tip over" in the wind.
Pipe bore is the actual minimum inside diameter of a pipe, which is not necessarily the nominal pipe size.
What is your motivation for applying for graduate engineer?
Do your best and try your hardest, because you can do anything if you put your mind to it.
