It's hard to know where to start with Ray Kurzweil. With the fact that he takes 150 pills a day and is intravenously injected on a weekly basis with a dizzying list of vitamins, dietary supplements, and substances that sound about as scientifically effective as face cream: coenzyme Q10, …
2 STROKE ENGINE & 4 STROKE ENGINE DIFFERENCE: In case of two stroke engine, rotation of crank shaft will be power stroke for every one rotation. During compression stroke, fuel will flow towards the crank case(suction) and during power stroke, exhaust will emit the burnt fuel through the transfer ports. While in case of four stroke engine, rotation of crank shaft will be power stroke for every two rotation. Moreover, suction compression power and exhaust strokes are separate as there will be inlet and exhaust valves. For more like Mechanical Engineers Rocks.
Significance of governor in automobiles: Governor is an important component of automobile engine. It is used to regulate the main speed of engine during the variations in loads. With the variations in the load, fuel supply has to be maintained. This task is performed by the governor. In the case of high load on the engine, speed decreases, hence fuel supply has to be increased and similarly when load decreases then the fuel supply has to be decreased.

Centrifugal Casting or rotocasting:- Is a casting technique that is typically used to cast thin-walled cylinders. It is noted for the high quality of the results attainable, particularly for precise control of their metallurgy and crystal structure. Unlike most other casting techniques, centrifugal casting is chiefly used to manufacture stock materials in standard sizes for further machining, rather than shaped parts tailored to a particular end-use. Process:- In centrifugal casting, a permanent mold is rotated continuously about its axis at high speeds (300 to 3000 rpm) as the molten metal is poured. The molten metal is centrifugally thrown towards the inside mold wall, where it solidifies after cooling. The casting is usually a fine-grained casting with a very fine-grained outer diameter, owing to chilling against the mould surface. Impurities and inclusions are thrown to the surface of the inside diameter, which can be machined away. Casting machines may be either horizontal or vertical-axis. Horizontal axis machines are preferred for long, thin cylinders, vertical machines for rings. For more join Mechanical Engineers Rocks. Don't Forget to join our new page Automobiles and Engines
Turbomachinery It describes machines that transfer energy between a rotor and a fluid, including both turbines and compressors. While a turbine transfers energy from a fluid to a rotor, a compressor transfers energy from a rotor to a fluid. The two types of machines are governed by the same basic relationships including Newton's second Law of Motion and Euler's energy equation for compressible fluids. Centrifugal pumps are also turbomachines that transfer energy from a rotor to a fluid, usually a liquid, while turbines and compressors usually work with a gas.

Most of my dreams are boring. I’m typically talking to someone I know, either on the phone or in person, in a familiar place. The conversations tend to include ideas that I’ve read about or experienced recently in my waking life. Some of my dreams don’t even have the intrigue of another character; …
Apple's "iOS in the Car" operating system, which would let drivers access various iPhone functions through a car's built-in screen, is set to head out of the garage next week, says a report.<p>Ferrari, Mercedes-Benz, and Volvo are the automakers on board for the launch, said the Financial Times, which …
