Flywheel

Flywheel
The flywheel is a disk or wheel attached to the crank, forming an inertial mass that stores rotational energy. In engines with only a single cylinder the flywheel is essential to carry energy over the power stroke into a subsequent compression stroke.  Flywheel mostly present in reciprocating engines to smooth out the power delivery over each rotation of the crank and in most automotive engines also mounts a gear ring for a starter. The rotational inertia of the flywheel also allows a much slower minimum unloaded speed and also improves the smoothness at idle .the flywheel may also perform a part of the balancing of the system and so by itself be out of balance although most engines will use a neutral balance for the fly wheel ,enabling it to be balance in a separate operation. The flywheel is also used as a mounting for the clutch or a torque converter in most automotive applications.
Material
Flywheel  are typically made by steel and also carbon fiber is used because of tensile strength will yield the highest energy storage per unit mass.

The blood would appear  green  in color in deep sea/ocean. Water can  boil  and  freeze  at the same time. If you took out all the  empty space  in our atoms, the human race could fit in the  volume of a sugar cube . Lasers can get  trapped  in a waterfall. A  teaspoonful  of neutron star would weigh  6 billion tons . The Eiffel Tower can be  15 cm  taller during the summer. Babies have around  100 more bones  than adults. An egg looks like a  crazy jellyfish  underwater. A flea can  accelerate faster  than the Space Shuttle. A single solar flare can release the equivalent energy of  millions of 100 megaton atomic bombs . Cats always land on their  feet . If you  spin  a ball as you  drop  it ,  it  flies .

FIFA WORLD CUP HISTORY

Image
Federation International The Football Association The success of the Olympic Football Tournament intensified FlFA's wish for its own world championship. Questionnaires were sent to the affiliated associations, asking whether they agreed to the organization of a tournament and under what conditions. A special committee examined the question, with President Jules Rimet the driving force. He was aided by the untiring Secretary of the French Football Federation, Henri Delaunay. Following a remarkable proposal by the Executive Committee, the FIFA Congress in Amsterdam on 28 May 1928 decided to stage a world championship organized by FIFA. Now, the organizing country had to be chosen. Hungary, Italy, the Netherlands, Spain and Sweden submitted their candidatures. Right from the start, Uruguay was the favorite and not simply for its Olympic gold medal wins in 1924 and 1928 - the country was celebrating its 100th anniversary of independence in 1930 at great expense. Moreover, it...

CRANKCASE

http://en.wikipedia.org CRANKCASE         The main body of the engine to which the cylinder are attached and which contains the crankshaft and crankshaft bearings is called crankcase.This members also holds other parts in alignment and resists the explosion and intertia forces.It also protects the parts from dirt etc. In the crankcase only the engine oil are stored in self lubricate syst em the crankcase play an important role the scoop used for splashing to the engive wall are taking oil from the crankcase only so I play a majore role in lubrication system      Crankcase forming an engine block ,crankcase  are the basic engine structural component   crankcase often has an opening in the bottom to which an oil pan is attached a gasketed bolted joint. Material used for crankcase  Material which is used for making crankcase are engine block mostly cast aluminium crankcase are made via sand casting ...
