Sentence examples for wing stroke from inspiring English sources

The thrust and drag generations are complicated functions of frequency and wing stroke motions.

To compensate, the researchers found, montane hummingbirds have relatively larger wings and reach farther with each wing stroke.

They adapt to higher elevations by extending their wing stroke amplitude.

Because the wings are in rotary motion, the maximum kinetic energy during each wing stroke is: KE= \frac12 I\omega_\text {max}^2 Here I is the moment of inertia of the wing and ωmax is the maximum angular velocity during the wing stroke.

In flight, it has a deeper, slower wing stroke than other waders of a similar size, and displays a thin, indistinct white bar on the wing, and white ovals on the sides of the tail.

Therefore: :v_{av}=\frac{d}{\Delta t}=\frac{0.57}{4.5\times10^{-3}}=127\Thet {cm/s} The velocity of the wings is zero both at the beginning and at the end of the wing stroke, meaning the maximum linear velocity is higher than the average velocity.

The passage of time has dyed them a Champagney hue; as they slowly rise and fall they bring to mind the intermittent wing strokes of some great hovering bird.

The instruments measured the depths, speed, and acceleration and deceleration effects from wing strokes for more than 650 dives.

West and King showed that, amongst other processes, male song is shaped by feedback from female cowbirds, whose wing stroking and gaping displays in response to the songs they prefer are strong reinforcers for males.

Therefore, the maximum angular velocity is: : \omega_\text {max}=\frac{254}{\ell/2} And the kinetic energy therefore is: KE = \frac12 I\omega_{max}^2=\left ( 10^{-3} \frac{\ell^2}{3} \right ) \left ( \frac{254}{\ell/2} \right )^2 = 43 \text { erg} Since there are two wing strokes (the upstroke and downstroke) in each cycle of the wing movement, the kinetic energy is 2×43 = 86 erg.

Indeed, the elbow angle is likely varied in flight and during a wing-stroke [15], [16].
