Women gymnasts are able to engage in rhythmic Gymnastics as an event in addition to the other events that are offered. With a style that is similar to a dancing routine, it also combines together aspects that are acrobatic with props as well. The types of props vary, but must be within certain guidelines in order to be used in a rhythmic routine.

The primary purpose of the rhythmic routine is to emphasize the athletes ability show power, strength, endurance, flexibility, agility and even dexterity while still controlling the prop and keeping up with the actual routine. This can sometimes be a very difficult concept for many gymnasts to grasp however; it is a very entertaining style that catches many people’s attention.

The first piece of apparatus or prop as they are called is a rope. This is used by swinging the rope around to create circles, wraps and various other movements. Often times the rope is tossed into the air while the gymnasts jumps and twirls and other times they simply swirl the rope around.

When using the hoop the gymnast can roll it, toss it into the air, spin the hoop around, move through the hoop, and even move around. In addition, many gymnasts enjoy spinning the hoop around various body parts while performing other tricks to show off their overall abilities to the judges and audience. Many advanced rhythmic gymnasts also combine high throws with various other acrobatic techniques to create a visually impressive routine.

Another piece of apparatus is the ball. This is used mostly for throws, catches, circles, and even a few waves. Most movements with the ball involve the use of the hands; however, skilled gymnasts may learn to control the ball using various other parts of their body to create stunningly impressive displays.

Clubs are another apparatus that is used in rhythmic Gymnastics . The purpose of the clubs is to toss in the air and perform various tricks with them. Often compared to the clubs that clowns use for juggling they are not very small and can sometimes be quite bulky. Many of the routines that involve the clubs tend to focus around tapping and throws as well as catches above any other aspect.

The last piece of apparatus that is allowed in rhythmic Gymnastics is the ribbon. This is used to create beautiful figure-eight movements as well as circles, throws and even spirals. As one of the more visually appealing apparatus in rhythmic Gymnastics , it is quite easy to allow the ribbon to hang close to the body in the various acrobatic positions creating a visually stunning impression.

Parachutes are fairly easy to make, as toy ones that is. However the parachutes that are made to use for real life is not as easy as you think. parachutes have gone through a lot of development but at the costs of several lives.

When you’re free falling thousands of feet up in the air you can fall like pot from a window and literally break when you smash into the ground. No one wants this to happen. parachutes have to made and prepared correctly. Fortunately modern designs have enabled safer and softer landings.

The shape of a parachute is very important. parachutes have come in different shapes through the years. Improvements have led to the creation of more stable ones in square shapes.

Shapes and surface area

The early forms before the modern design was invented were conically shaped. They were usually made up of cloth and wooden struts. The very first one was a conic shaped parachute stiffened by wooden struts in 9th century.

The inventor was able to make a landing from a tower in Cordoba and suffered only minor injuries. Leonardo da Vinci made sketches of them but there were no evidence that showed it was put to use.

It was also used for entertainment because it enabled people to jump and float to the ground which was very fascinating at that time. In China parasols were used for entertaining people. A breakthrough in the development was made when silk was used. This time parachutes were intended to be used for disembarking from a hot air balloon.

In 1783 the modern parachute was invented. The shape was round and was compared to the jellyfish. Its major use was in the military in World War I and II. It was given to artillery spotters and pilots. Unfortunately they were heavy in those times. Further developments lead to the creation of paratroopers. These were soldiers dropped into the enemy lines for attack.

There are variations to the round shape parachute. Additions were made for other purposes. Annular and pull down apex were round parachutes with suspension lines. Ribbon and ring designs on the other hand are made for deployment at super sonic speeds.

It later on developed into a cruciform or square shape which is also used in modern designs today. The design gave the parachute more stability. Further improvements enabled the passenger to steer the parachute to a landing site. Modern designs are called "Ram air" with parafoils that enable the skydiver to control the speed and direction of the parachute.

The shape of the parachute is important because of its relation to surface area.
