The Sports of Roller Skate

Roller skating might not be as common or popular as ice skating, bicycle or skateboard but it has got similar points of interest. Just like other similar equipment, roller skating has several forms of uses : recreational, sport or transportation. You certainly have an idea about how roller skating in its recreational or transportation forms look like, but how about in sport ? The sport is not yet an Olympic sport but is recognized by the U.S.O.C. (United States Olympic Committee) as a Pan American sport. Popular domain of sport such as speed, artistic, freestyle movement can also be find in roller skating. Let’s discover more about them.

Speed Skating

This sport is often called “Inline Speed Skating”, using inline skates. The sport is similar enough to ice speed skating and many competitors are known to switch between inline and ice speed skating according to the season.

Artistic Roller Skating 

This sport consists of several styles and are most often performed on quad skates :


Figure skating is when the skaters follow the black lines drawn on the skating floor. There are set patterns of movement you must follow around the circles while tracing the line.


Dance skating is a sport where a single person or a couple skate to a specific style of music (blues, tango, etc.). Technique, flow and how well they match as a team are important points in the judgement.
Free dance is the in the top categories of dance where the team chose the music. In free dance the lifts cannot go over the man’s head and there are no jumps as there are in pairs.

Roller Hockey


This sport is like ice hockey but played in a dry surface using roller skates.

Roller Derby


This is a contact sport where 2 teams of 5 members roller skate in the same direction around a track. Both teams designate a “scoring player” and they score points by lapping members of the opposing team.

It is always interesting to see how human’s creativity can always create a new game from one single equipment. If you’ve become interested in trying one of these activities, keep in mind that Shanghai Metal Corporation provides the materials needed to build your ideal roller skate. Our product has been analyzed, stress-tested, and refined to reduce weight, increase strength, and improve the feel.

New Japanese Maglev train !

Series_L0_PrototypeMaglev is a method of transportation which uses the magnetic levitation to carry vehicles with mag-nets rather than with wheels. Maglev trains move more smoothly and more quietly than the others ways of transportation. The power which is needed for levitation is not a large percentage of the overall energy consumption, the power is actually needed for overcoming the air-resistance.

Japanese invented high speed rail in 1964 with their first Shinkansen bullet train and nowadays they are coming with next generation of fast trains with its first public test! This new Maglev train can hit 311 mph using “L-Zero” technology. Passengers can get from Tokyo to Nagoya within 40 minutes. Public tests rides will begin this November when 178 mile (286 kilometer) route officially opens and there will be six stations.

“L-Zero” technology

“L-Zero” technology means that train speeds of around 100 mph (160km/h) before the engaging the maglev system and then slowly accelerating to the top speed 311 mph (500 km/h). Japanese want to successfully demonstrate that Maglev trains work properly because Japan wants to export this technology. Japenese government recently offered a $5 billion down payment to build a maglev train from Washington to Baltimore which would take just 15 minutes. But the only maglev train is now operating in Shanghai, China. This Shanghai Maglev train operates with 268 mph (431 km/h) speed and travels 19 miles (30.5 km) from the airport to the city within 8 minutes.

Do You Know How The UK Coins Are Made And What Are They Made of?

image

The processes involved in producing a coin can be broken down into three different sections: making the blanks, making the dies and striking the coins.

Making the blanks

Depending on the alloy required, the appropriate metals are melted in the necessary proportions in a furnace. The metal is then extracted from the furnace in the form of a continuous strip, which is cut to produce coils weighing up to 2.8 tonnes. The strip is passed through powerful rolling mills to reduce it to the thickness of a coin. Blank discs of metal are then punched from the strip in a blanking press at a rate of up to 10,000 a minute. Rolling metal under great pressure makes it hard so the blanks have to be softened, something which is achieved by heating them in an annealing furnace at up to 950°C.

Making the dies

Once a design has been approved, a plaster model is prepared at several times the diameter of the intended coin. The plaster model is scanned by a ruby-tipped probe which records the design as a digital file on a computer. Guided by this digital file, an engraving machine cuts the design into a piece of steel at the correct size of the coin. Known as a reduction punch, this piece of steel is then used to make the dies which will actually strike the coins.

Striking the coins

For the final stage of the process, the blanks are fed into a coining press containing a pair of dies. Applying a pressure of around 60 tonnes, the dies strike the blanks and turn them into coins at speeds of up to 850 a minute.

What?! Car Flying Over London?

You probably have seen Smart Cars jumping over a bridge every single day in Rotterdam but I bet you haven’t seen the 2015 Jaguar XE flying over central London in the beginning of this month.

In collaboration with the British Royal Air Force Red Arrows Acrobatic Team the car was air-lifted by helicopter in Solihull, where Jaguar’s manufacturers is located and carried along the Thames to Tower Bridge. The car continued its trip on a boat to later on hit the Earls Court, the home of 14 Jaguar debuts since 1935, where it was escorted by two 1960’s Mark II Jaguar Police Cars and welcomed by the 3,000 excited VIP guests.

The show was narrated by English actor, John Hannah and included a star-studded performance lineup including Emeli Sande, The Kaiser Chiefs, Eliza Doolittle, the Royal Ballet, members of the London Philharmonic Orchestra and Max Milner from The Voice.

What so special about the cutting-edge £30,000 XE sports car is the aluminum-intensive materials used to build the car, making it lightweight, stiff and sleek profile. The aluminum-lighter body makes the car more potential-fuel conscious, which in turn comes in line with efficiency regulations. Other carmakers such as Ford have chosen to use nearly all aluminum metal body in its most profitable vehicle, F150. The fact is aluminum when combined with small amounts of other metals to form and alloy it is actually just as strong as steel.

Highly aerodynamic and powerful due to it six cylinder motor, Jaguar XE generates 450 pounds-feet of torque, allowing it to go from zero to 100 km/h in less than 5 seconds and hit an electronically limited maximum speed of 155 mph. The XE car has a luxurious interior and advanced infotainment system including an eight-inch touchscreen and a clear graphical interface.
