Where does dynamic equilibrium take place?
Where the energy going into a system equals that going out of it. An aircraft in steady, level flight is in equilibrium: Thrust=Drag, and Lift=Weight.
Can you lift your own weight?
it is proven that you can lift your weight or more And you can push nearly 2 times more with your legs!
How do aircraft fly?
There is two categories of aircrafts, the aerostats (lighter than air) and the aerodynes (heavier than air). -Aerostat: the aerostat uses buoyance to float in the air in much the same way that ships float on the water.They are characterized by one or more large gasbags or canopies, filled with a relatively low density gas such as Helium, Hydrogen, or Hot air which is lighter than the surroundind air. When the weight of this is added to the weight of the aircraft structure, it added up to the same weight as the air that the craft displaces. -Aerodyne: To fly it must move forwards through the air ,this movement of air over the aerofoil shape deflects air downward to create an equal opposite upward force, called lift, according to the Newton's third law of motion. Aerodyne flight: The best method to answer this question is thru the use of the lift formula: L= (1/2p) (V2) (S) (CL) 1/2p (pronounced rho) is basically the density of the air. Cool dense air provides better pressure in creating lift. V2 is the velocity of the airfoil flowing thru the air. Higher velocity creates more lift except when reaching velocities that exceed the sound barrier disrupting laminar flow over the airfoil. S is the surface area of the airfoil. A larger surface area creates more lift. It may also create more weight which would increase the need for more lift. CL is the coefficient of lift. Without getting to complicated, this is basically the efficiency of the airfoil design at an angle of attack. Angle of attack is essentially the angle between the chord line of the airfoil and air flow direction. When air flows over the airfoil, the design of the foil seperates the airflow into an area of low pressure over the camber of the airfoil, and an area of high pressure below it. Obviously the difference between the two areas will cause the movement of the airfoil in the direction of low pressure thus creating lift. Their are four forces at work in the creation of lift: Lift - Explained above Thrust - The force required to move the craft forward to create velocity of airflow. Drag - The force created from the creation of lift and thrust. Parasitic, Induced, and Profile drag are the different types of drag working against lift. Weight / Gravity - What must be overcome by lift.
In newtons 3rd law how many forces always act at once?
Two - forces act in pairs. If object "A" acts on object "B", the object "B" will also act on object "A". In many practical situations, there may be additional forces involved. For example, if an object is at rest despite the fact that a force acts on it, then it is obvious that an additional force acts on the same object, and in the opposite direction. In such cases, there are at least four forces involved, since according to Newton's Third Law, there must be an opposite force for each of these two forces. (Note that in Newton's Third Law, the two forces act on DIFFERENT objects, so the two forces that hold an object in balance do not quality as a pair of forces according to Newton's Third Law.)
What does hefted mean?
Weight; heaviness or bulk. Also, to lift something.
What are the four forces that act on an airplane in flight?
Lift, weight, thrust and drag.
What is the relationship of lift drag thrust and weight when the airplane is in straight-and-level flight?
Lift equals weight and thrust equals drag.
What are the forces on an airplane?
There are four forces that act on an airplane that keeps it at a level altitude. Thrust, drag, weight, and lift determine whether a pilot flies at a level altitude.
What is the relationship between the 4 forces of flight?
Lift is opposite of weight Thrust is opposite drag. When lift >weight plane climbs. If lift < weight you best find a place to land. If thrust> drag you accelerate. If drag>thrust you slow down. High and fast are your friends. Low and slow are out to kill you.
