The reservoir falls in a spiral beca habit of the aerodynamic shape of the wing-like complex body part of the seed. This structure has the appearance of the wing of a dragonfly. The maple seed itself is at mavin end with the wing attached at the other end. The maple seed end is heavier, and this causes the seed to twirl as it falls. The twirling slows down the seed and allows it to catch a crosswind that will carry it farther out-of-door in order to disperse it.
It is similar to a propeller because of the wing of the seed has the shape of one blade of the propeller fan. I could help students to understand how a propeller works or why the maple seed twirls when it falls by explaining the opinion of air resistance and surface area.
The maple seed falls tardily down to the ground because of the low air stuff that is created vertical in a higher place the thicker edge of the wing of the maple seed. This low air pressure results from the motion of the wing as it travels down in a spiral. This air pressure is actually a tornado-like vortex that is created above the thicker edge of the wing.
This vortex gives an upward push to the maple seed in the opposite direction of gravity. This makes the descent of the seed take more than time and so it is in the air or brief and twirling through the air till it finally reaches the ground. This principle is the selfsame(prenominal) that is used to keep helicopters in the air. Engineers have devised a monocopter with a single wing similar to the maple seed and have been prospering in keeping it aloft in the air with the use of remote control as well as a motor.
The Wright brothers used the principle of air resistance in the maple seed fall to design their propeller which was the first successful essay at flight by man. The propeller works under the...If you want to get a full essay, order it on our website: Orderessay
