Fever of FIFA World Cup 2014 is ON all around the world, it seems that everyone involved in football. The reason behind that much interest may partly contribute to the football used in the last wc, which really did not get along with all the players and the Brazilian striker luis fabian called the supernatural, when he moves the ball. Today, football is named Brazuca, according to Adidas and manufactured in Pakistan.
You will be surprised to know the amount of effort and research is made up of this world-famous football tournament. Football is not just a field, but the object of which should be studied carefully and should be adjusted aerodynamics. Flight of the ball through the medium (air) to study the aerodynamic forces and itself includes many scientific phenomena.
In simple words; the thin layer formed on the surface of the ball in the air when it moves in the air and this layer is known as the boundary layer, which includes all of ball. The pressure circulation on the surface can practice ball crazy.
The most difficult challenges facing adidas came pressed effect (hit the ball without rotation and the route is determined by the pressure division). To meet the desired requirements the only solution found that roughen the surface of the football and use the six panels, while the football stitching together.
Making sure no stone left unturned, scientists at NASA AMES research center and decided Brazuca employed in the wind tunnel, water channel in partnership with laser and fluorescent dye to show clearly and simulate the forces acting on the ball when it was in flight. Director of the experimental department Rabi Mehta, said "what do you gaze for patterns of tobacco smoke is a sudden change in speed standards. These is compressed when the effects are great."
These findings led to the conclusion that Brazuca, the optimal speed of only 30mph pressed while the average speed of a player strike wc 50-55 mph and, therefore, limits the speed of the ball is pressed Brazuca much more predictable and stable. Rabi said "The players will enjoy and happy with the new ball. 'S a more stable flight and to cope with the more traditional ball 32-panel.
Team nasa is not the only group that resolution Brazuca, we have a team of mit, who has control of the ball. According to the study, this group, with a rough surface allows the legs to cope with the magnus effect, as well. For those of you not aware of this phenomenon, magnus effect when the ball spins in the opposite direction, where it was shot spin.
There you have it folks; Brazuca has definitely passed with flying colors and we are eager to see how this particular ball to perform at the fifa world cup 2014.
