Conclusion: Graph 1 shows patterns observed with parachute shape. The patterns observed are that the octagon has much slower speed than all the other shapes. The rectangle shape parachute is the fastest speed. The R squared value looks at the points of data and their variations to determine a strong or weak correlation. The rectangle shows the weakest points of data and the octagon shows the strongest points of data. It is noted that no control run is conducted in this experiment. When trialing

. Today‚ I would like to present to you on the topic‚ the comparison between helicopters and an airplanes. As we all know‚ both are an extrodinary aviation miracle. A hundred years back‚ who would have though of the possibility of a man flying? Thanks to the Wright Brothers‚ this dream is now a living marvel. Wether it is a helicopter or a plane‚ they both share the same purpose of making our life easier. Besides that‚ they both uses the same basic principle of flight which are aerofoil and

On 14th of October 2012‚ the famous Austrian skydiver‚ daredevil‚ and BASE Jumper‚ “Fearless” Felix Baumgartner broke a world record of the highest skydive jump‚ on a mission called Red Bull Stratos‚ also known as Mission to the edge of space. The number of world records aimed to be broken in this mission was 4‚ but Felix only broke 3 world records‚ due to his faster free fall time. In this jump he ascended to the stratosphere in a capsule carried by a helium balloon up to 127‚851 ft. (38‚969 m)

Mechanisms of Multicolored Striped Toothpaste Aree Witoelar Toothpastes often use two or more colors to form stripes. While not providing hygienic benefits‚ it has interesting appearance for the customer [1]. Here we investigate and discover two different mechanisms to achieve consistency of the color ratios. Two sample tubes of toothpaste are chosen randomly from the market‚ and labeled as A and P (Figure 1). The samples are cut across the toothpaste compartment (Figure 2). (not shown). The

The breaking of water stream under the light of total internal reflection of laser Jiho Yang Colegio Retamar Abstract In this paper‚ we report the circumstances that produce breaking of water stream. The usual way to visualize this is by using a strobe‚ as how they do in Science museums. Experimental methodology that we have used to investigate this topic is based on an experiment carried out by two scientists in 1850 that contributed to studies about total reflections. By using a laser

LIFT‚ DRAG AND MOMENT OF A NACA 0015 AIRFOIL by Steven D. Miller DEPARTMENT OF AEROSPACE ENGINEERING THE OHIO STATE UNIVERSITY 28 MAYi 2008 ABSTRACT A NACA 0015 symmetrical airfoil with a 15% thickness to chord ratio was analyzed to determine the lift‚ drag and moment coefficients. A 2D airfoil was placed in a low speed wind tunnel with pressure taps along its surface and a pitot probe downstream to measure the flow characteristics. The wind tunnel was operated at a nominal 17 m/s during

Edgar Xiong David Blackburn Period 3 Physics of Flight One may wonder‚ what is flight? Many just stare up into the blue skies above and assume. while others devote their lives to discovering and finding a passion in aviation. Flight can be simply characterized as the [powered] gliding of an object through the air‚ but the wonders of soaring through the air does not simply stop there‚ instead‚ flight is a whole myriad of forces acting on each other‚ as so found out by scientists decades

ABSTRACT The aim of this experiment is to study the friction loss along a pipe. In this experiment‚ water and mercury have been used to demonstrate the law of resistance with different types of flow which are laminar and turbulent flow. The variation of head loss will be obtained and hence determined the Reynold numbers and friction factor. In the end of the experiment‚ the law of resistance which is the relationship between i and u will be determined and hence established the critical R and friction
