Flywheel

A flywheel is a rotating mechanical device that is used to store rotational energy. Flywheels have a significant moment of inertia and thus resist changes in rotational speed. The amount of energy stored in a flywheel is proportional to the square of its rotational speed. Energy is transferred to a flywheel by applying torque to it, thereby increasing its rotational speed, and hence its stored energy. Conversely, a flywheel releases stored energy by applying torque to a mechanical load, thereby decreasing its rotational speed.

Common uses of a flywheel include:

• Providing continuous energy when the energy source is discontinuous. For example, flywheels are used in reciprocating engines because the energy source, torque from the engine, is intermittent.
• Delivering energy at rates beyond the ability of a continuous energy source. This is achieved by collecting energy in the flywheel over time and then releasing the energy quickly, at rates that exceed the abilities of the energy source.
• Controlling the orientation of a mechanical system. In such applications, the angular momentum of a flywheel is purposely transferred to a load when energy is transferred to or from the flywheel.

Flywheels are typically made of steel and rotate on conventional bearings; these are generally limited to a revolution rate of a few thousand RPM.Some modern flywheels are made of carbon fiber materials and employ magnetic bearings, enabling them to revolve at speeds up to 60,000 RPM.

wagon r STINGRAY

Maruti Suzuki India Ltd, the country's largest passenger car manufacturer, never fails to amaze us. The last time we wrote about them it was about Maruti Ertiga CNG that help Indian car-owners beat rising fuel prices and the Maruti Suzuki app for car serving. This time around, the automobile industry is getting a new entrant. With the upcoming launch of Maruti Suzuki Wagon R Stingray hatchback rumored to be around end of August this year or during the festive season as sales for passenger cars normally see a substantial increase at that time, there's much excitement among the folks who love unveiling of cars.

We all are aware of the fact that Maruti Suzuki's Wagon R has been popular on the Indian roads and it still sells on an average 13000 units per month. So, the all new Wagon R Stingray is among a lot of speculations about the features that it is going to sport. There was also news about the hatchback being spotted in a photography session and a demo version of the new car was seen at a Maruti Suzuki dealership. What took to everyone's attention was the huge Experience Stingray logo on a new chrome strip. The overall sporty look and feel of the Suzuki Wagon R Stingray has a bold front fascia that makes it look more masculine
Much is being written about the new Wagon R and its features - such as it features a bonnet with a large dam, slim headlamps, revised fog lamp clusters and a slim chrome grille. Running on four grey-finish alloy wheels, new rear spoiler and sleek tail lamps, the car has a kind of aggressive look that's just out there. Coming to the interiors, we are reading about black upholstery, high quality floor mats, an advanced audio system, electronically adjustable optical rear view mirrors, projector headlights, Anti-lock Braking System (ABS) and airbags.

The Maruti Suzuki Wagon R Stingray specifications may resemble mostly with the current Wagon R running on the roads. Therefore, we might see three-cylinder K Series 1-litre petrol engine that will be mated to a 5-speed manual gearbox. Though there's no official word about the price or the availability of this new car, according to reports, the hatchback's price in India could be around Rs. 4.10 lakh. So are the recently launched nissan micra and micra-active 2013 as well as hyundai grand i10 the competitors to the Wagon R Stingray? We will find out in due time. Let us know your views about the upcoming hatchback in the Indian car market through comments below.

Update: The car is going to feature tilt-adjustable steering wheel and electrically adjustable rear view mirrors. The KB 10B 1-litre engine produces 68PS of power and 90Nm of torque. Top-spec Vxi (O) gets driver-side airbag and ABS. A fuel economy figure of 20.51 kmpl for the Wagon R Stingray is being claimed.
