  2. Insect flight - Wikipedia

    en.wikipedia.org/wiki/Insect_flight

    To restore the insect to its original vertical position, the average upward force during the downward stroke, F av, must be equal to twice the weight of the insect. Note that since the upward force on the insect body is applied only for half the time, the average upward force on the insect is simply its weight. [14]

    The forelegs are reduced in the Nymphalidae Diagram of an insect leg. The thorax, which develops from segments 2, 3, and 4 of the larva, consists of three invisibly divided segments, namely prothorax, metathorax, and mesothorax. [11] The organs of insect locomotion – the legs and wings – are borne on the thorax.

  4. Flying and gliding animals - Wikipedia

    en.wikipedia.org/wiki/Flying_and_gliding_animals

    There are two basic aerodynamic models of insect flight. Most insects use a method that creates a spiralling leading edge vortex. [19] [20] Some very small insects use the fling-and-clap or Weis-Fogh mechanism in which the wings clap together above the insect's body and then fling apart. As they fling open, the air gets sucked in and creates a ...

    Insect morphology is the ... the meron of the middle leg appears as a large lobe of the coxa projecting upward and posteriorly from the coxal base; in higher members ...

  6. Coriolis force - Wikipedia

    en.wikipedia.org/wiki/Coriolis_force

    The centrifugal force acts outwards in the radial direction and is proportional to the distance of the body from the axis of the rotating frame. These additional forces are termed inertial forces, fictitious forces, or pseudo forces. By introducing these fictitious forces to a rotating frame of reference, Newton's laws of motion can be applied ...

    The upward tilt of the wings and tailplane of an aircraft, as seen on this Boeing 737, is called dihedral angle Flight dynamics is the science of air and space vehicle orientation and control in three dimensions.

  8. Lift (force) - Wikipedia

    en.wikipedia.org/wiki/Lift_(force)

    Lift conventionally acts in an upward direction in order to counter the force of gravity, but it is defined to act perpendicular to the flow and therefore can act in any direction. If the surrounding fluid is air, the force is called an aerodynamic force .

  9. Archimedes' principle - Wikipedia

    en.wikipedia.org/wiki/Archimedes'_principle

    Archimedes' principle states that the upward buoyant force that is exerted on a body immersed in a fluid, whether fully or partially, is equal to the weight of the fluid that the body displaces. [1] Archimedes' principle is a law of physics fundamental to fluid mechanics .
