### Tetrahedron Kite

By Tiffany

Summary
• We will be making kites with 45 inch and 25 inch string, straws. We have to make 4 pyramid,
What I Would Like To Learn
• I would like to learn how to make a tetrahedron kite
• I would also like to learn the history of it
Basics Of FlightDrag, Lift, and Thrust
• To comprehend the biomechanics of flight, a few simple physical principles must be kept in mind. First we have to recognize that air is a fluid, just like water. It is not a liquid, like water, but is a called a fluid because the force needed to deform it depends on how fast it is deformed, not on how much it is deformed (try moving your hand quickly, then slowly through a basin of water for an example). Solids are substances for which the force needed to deform the substance is dependent on the extent of deformation rather than the rate of deformation (so it takes the same amount of force to break a pencil quickly as it does to do it slowly; try this with a pencil that is devoid of sentimental value to you). As is common in nature, there are subtle gradations between the artificial dichotomy of fluids and solids; we have given you a generalized definition for each of the two ends of the continuum. We'll use "fluid" interchangeably with "air" here, and "object" interchangeably with "animal."
Different Types Of Kites
• The Sled Kite
• The Diamond Kite
• The Barn Door Kite
• The RokkakuKite
• The Sode Kite
• The Delta Kite
• The Roller Kite
• The DoperoKite
• The Tetrahedron Kite
Comparison /Differences
• Kites are much smaller than other things that can fly such as airplanes and helicopters.
• Airplanes and helicopters are bigger
• Kites depend mostly on wind.
• Airplanes and helicopters use motors.
• Kites Can’t Carry People.
• Airplanes and helicopters can carry people
