Figure 1 below shows the change in magnitude of the steady state acceleration with time. This graph complies with Newton’s second law as the force applied is equal to 1 and the mass remains constant so and an acceleration of one is expected. I also tested this by changing the value of the force applied‚ to a value of 2‚ which in theory should give and equivalent change in the acceleration‚ to a value of 2. From Newton’s second law: it can be seen that as the force varies‚ provided moment of inertia

This egg drop experiment forced me to think and develop a design that I felt confident with. I developed several models and tested them numerous times‚ but could not settle on one. Eventually‚ I was able to put an addition onto one of my designs which gave me confidence in its ability to protect that precious egg. I will explain why my design worked so well in respect to impulse‚ air resistance‚ and stability. First‚ I will discuss impulse. Impulse is a force acting briefly on a body and producing

Research What is a GLIDER? : A light engineless aircraft designed to glide after being towed aloft or launched from a catapult. Parts of Glider : A glider consists of three main parts: 1) Fuselage 2) Wing 3) Tail FUSELAGE: It can be defined as the main body of the glider. It is cambered and in the middle portion‚ we attach the wing around the position where the camber is maximum by either making a slot in the fuselage‚ or by dividing in two parts. WING: It is the most important part of

The lift on the aerofoil will also be calculated and compared with the theoretical value. The aerofoil being used in this particular experiment is

Part three Explaining how a thicker wing can be lighter than a thin wing when both are built for the same purpose: Firstly‚ the principle applying to the mass and thickness of wings applies to any aerofoil surface in any shape or form. How do we know a delta wing and a swept wing have heavier masses than a straight wing? Two important things need to come into account when measuring the thickness and weighing certain types of wings‚ the structural ‘Aspect Ratio’ and the ‘Thickness Ratio’ of aerofoil

Andrew MacGillivray January 31‚ 2013 Golf Fundamentals Anthony Back Spin and Bounce Backspin: Is the backward rotation of the ball on its horizontal axis. Back Spin is influenced and is determined by the loft/degree of the club face‚ the angle of your approach‚ and the speed or velocity of the club head. To create back spin on you must strike the ball below the horizontal axis. The trajectory of the shot involves an upward force that lifts the ball. A well struck shot will result in a large

When talking about the most efficient air bag we are talking about using the least amount of chemicals to make the most carbon dioxide to inflate the bag. We hypothesized that a small amount of sodium bicarbonate with a small amount of acetic acid will create enough carbon dioxide to inflate the bag so Humpty

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

Pressure Distribution around a Symmetric Aerofoil Abstract: The following report is based on an experiment conducted to calculate the lift curve slope for a symmetrical aerofoil subjected to varying angles of attack. Pressure readings were taken at different points on the upper and lower surface of the aerofoil. The report concludes that maximum lift is generated between 12 º -15º‚ which is also the stall point. It also states that region close to the leading edge contributes most to the lift force
