He also frequently uses the upstroke as opposed to the down stroke, especially on the high strings ( strings B and E ).
32.
Theoretically, the flapping wing can be set to zero angle of attack on the upstroke, so it passes easily through the air.
33.
The stored energy in the two wings is 36 erg, which is comparable to the kinetic energy in the upstroke of the wings.
34.
The pigeon had particularly large breast muscles that indicate powerful flight ( musculus pectoralis major for downstroke and the smaller musculus supracoracoideus for upstroke ).
35.
This, coupled with a limited upstroke caused by a lateral position of the shoulder joint, would have made it difficult to gain altitude.
36.
Patients may also present with varying degree of disability and symptoms, such as experiencing more difficulty writing down-stroke as compared to writing upstroke.
37.
On upstroke, a vacuum is created in the pipe under the operator's hand and the column of mud in the pipe is lifted.
38.
Guitarist Peter Buck plays the palm-muted lower strings of his guitar, marking the end of a four-bar repetition with an upstroke strummed chord.
39.
Since there are two wing strokes ( the upstroke and downstroke ) in each cycle of the wing movement, the kinetic energy is 2?3 = 86 erg.
40.
The two condyles, the upper one the largest, would have forced the finger into the most optimal plane of movement during the upstroke of the wing.
