World's Biggest Enginee

The Wartsila-Sulzer RTA96-C Maximum power: 108,920 hp at 102 rpm Maximum torque: 5,608,312 lb/ft at 102rpm The Wartsila-Sulzer RTA96-C turbocharged two-stroke diesel engine is the most powerful and most efficient pri me-mover in the world today. The Aioi Works of Japan 's Diesel United, Ltd built the first engines and is where some of these pictures were taken. It is available in 6 through 14 cylinder versions, all are inline engines. These engines were designed pri marily for very large container ships. Ship owners like a single engine/single propeller design and the new generation of larger container ships needed a bigger engine to propel them. The cylinder bore is just under 38" and the stroke is just over 98". Each cylinder displaces 111,143 cubic inches (1820 liters) and produces 7780 horsepower. Total displacement comes out to 1,556,002 cubic inches (25,480 liters) for the fourteen cylinder version.   Some facts on the 14 cylinder version: Total engine weight: 2300 tons (The crankshaft alone weighs 300 tons.) Length: 89 feet Height: 44 feet Maximum power: 108,920 hp at 102 rpm Maximum torque: 5,608,312 lb/ft at 102rpm Fuel consumption at maximum power is 0.278 lbs per hp per hour (Brake Specific Fuel Consumption) . Fuel consumption at maximum economy is 0.260 lbs/hp/hour. At maximum economy the engine exceeds 50% thermal efficiency. That is, more than 50% of the energy in the fuel in converted to motion. For comparison, most automotive and small aircraft engines have BSFC figures in the 0.40-0.60 lbs/hp/hr range and 25-30% thermal efficiency range. Even at its most efficient power setting, the big 14 consumes 1,660 gallons of heavy fuel oil per hour. A cross section of the RTA96C: The internals of this engine are a bit different than most automotive engines. The top of the connecting rod is not attached directly to the piston. The top of the connecting rod attaches to a "crosshead" which rides in guide channels. A long piston rod then connects the crosshead to the piston. I assume this is done so the the sideways forces produced by the connecting rod are absorbed by the crosshead and not by the piston. Those sideways forces are what makes the cylinders in an auto engine get oval-shaped over time. Installing the "thin-shell" bearings. Crank & rod journals are 38" in diameter and 16" wide: The crank sitting in the block (also known as a "gondola-style" bedplate). This is a 10 cylinder version. Note the steps by each crank throw that lead down into the crankcase: A piston & piston rod assembly. The piston is at the top. The large square plate at the bottom is where the whole assembly attaches to the crosshead:   Some pistons: And some piston rods:     The "spikes" on the piston rods are hollow tubes that go into the holes you can see on the bottom of the pistons (left picture) and inject oil into the inside of the piston which keeps the top of the piston from overheating. Some high-performance auto engines have a similar feature where an oil squirter nozzle squirts oil onto the bottom of the piston. The cylinder deck (10 cylinder version). Cylinder liners are die-cast ductile cast iron. Look at the size of those head studs!: The first completed 12 cylinder engine:

Shayri 4 All...

Mil Jaye Koi Naya To Hume Na Bhula Dena
Koi Rula de Tumhe To Hume Yaad Kar Lena ,
dost na sahi Hum tumhare,…….....insaan to hai...
Khushi Na Sahi YAAR , Gum Hi Baant Lena...!! 

__________________________________________________________

Jab bhi aapki yaad aati hai, 
mere honthon pe ye fariyad aati hai,
khuda khush rakhe aapko hr haal me, 
kyunke hmari khushi to aaj bhi aap ki khushi ke baad aati hai.

__________________________________________________________

wada karte hai kasme khate hai,
fir bhi na jane log kyu sath chod dete hai,
hume to takleef hoti hai phool todne me bhi , 
log na jane kaise kaise dil tod dete hai.

___________________________________________________________

Kisi na kisi pe kisi ko aitbar ho jata he,
Ajnabi koi shaks yaar ho jate he, 
Khubiyose nahi hoti mohabbat sadaa, 
Khamoshiyose bhi aksar pyar ho jata he.

World's Longest Keyboard

World's Longest Keyboard

22,528 recycled computer keycaps and 192 custom keycaps, fabric, customized active keyboard and interactive software, video projection and painted aluminum armatures

2.6 ft h x 4 ft w x 20.4 ft d

Permanent Collection of Fabric Workshop and Museum, Philadelphia, PA

In this interactive sculpture, thousands of recycled keyboard keys are embedded into a continuous textile. The keys spell out a line-by-line transcript of the email correspondence between the artist and fabricators regarding the creation of the artwork. As a result, the sculpture documents its own making. Viewers can also type their own messages on the active keys amid the first three rows of emails. These new messages are then projected onto the opposite end of the fabric, thereby continuing the virtual dialogue. The project speaks to the pervasiveness of email in our lives while commenting on the fact that, despite the modern technology of virtual communication, our written language is linked to the tactile sensation of moving our fingers over an outmoded typewriter system.

Some Important Laws Which Newton Forgot to State

LAW OF QUEUE: If you change queues, the one you have left will start to move faster than the one you are in now.

 

LAW OF TELEPHONE: When you dial a wrong number, you never get an engaged one.

 

LAW OF MECHANICAL REPAIR : After your hands become coated with grease, your nose will begin to itch.

 

LAW OF THE WORKSHOP: Any tool, when dropped, will roll to the least accessible corner.

  

LAW OF THE ALIBI: If you tell the boss you were late for work because you had a flat tire, the next morning you will have a flat tire.

LAW OF ENCOUNTERS: The probability of meeting someone you know increases when you are with someone you don't want to be seen with.

LAW OF THE RESULT: When you try to prove to someone that a machine won't work, it will!

LAW OF BIOMECHANICS: The severity of the itch is inversely proportional to the reach.

THEATRE RULE: People with the seats at the furthest from the aisle arrive last.

What is Life Partner....

Why should the wedding ring be worn on the fourth finger? 

There is a beautiful and convincing explanation given by the Chinese..... 

Thumb represents your Parents 

Second (Index) finger represents your Siblings 

Middle finger represents your-Self 

Fourth (Ring) finger represents your Life Partner 

& the Last (Little) finger represents your children 

Firstly, open your palms (face to face), bend the middle fingers and hold them together - back to back 

Secondly, open and hold the remaining three fingers and the thumb - tip to tip 

(As shown in the figure below): 

Now, try to separate your thumbs (representing the parents)..., they will open, because your parents are not destined to live with you lifelong, and have to leave you sooner or later. 

Please join your thumbs as before and separate your Index fingers (representing siblings)...., they will also open, because your brothers and sisters will have their own families and will have to lead their own separate lives. 

Now join the Index fingers and separate your Little fingers (representing your children)...., they will open too, because the children also will get married and settle down on their own some day. 

Finally, join your Little fingers, and try to separate your Ring fingers (representing your spouse). 

You will be surprised to see that you just CANNOT....., because Husband & Wife have to remain together all their lives - through thick and thin!! 

Please try this out.............
