angular difference 예문

• From this, the various angular differences can be calculated in the power flow equations.
• For each animal, the angular difference between its orientation and the group orientation is then found.
• As the planet gets closer to the earth it will shrink in appearance from a crescent to only showing the dark side when the angular difference is zero.
• The angular difference between "'true "'and "'magnetic "'north is called deviation which varies by vessel and its heading.
• Reaction time to determine whether they were identical or not was a linear function of the angular difference between their orientation, whether in the picture plane or in depth.
• The fish is trying to reduce its alignment " error ", meaning it is trying to stay as parallel as it can with the electric field and reduce the angular difference between the electric field and the angle of its body.
• Where \ mathbf n _ a and \ mathbf n _ b are the " n "-vectors representing the two positions " a " and " b " . \ Delta \ sigma is the angular difference, and thus the great-circle distance is achieved by multiplying with the Earth radius.
• The main disadvantage of both SACLOS guidance systems in an anti-tank role is that working on angular differences evaluation, it does not allow any notable separation between guidance system and missile launch post the opposite of MCLOS ones, thus allowing updated version of such anti-tank weapons ( notably AT-3 Malyutka ) to still remain in service in some countries.
• The first system to supplant ballistic pendulums with direct measures of projectile speed was invented in 1808, during the Napoleonic Wars and used a rapidly rotating shaft of known speed with two paper disks on it; the bullet was fired through the disks, parallel to the shaft, and the angular difference in the points of impact provided an elapsed time over the distance between the disks.
• Where " ? " is the angular difference of the course from the N S axis if the values of " ? " are less than 45? if, however, the angle exceeds 45? then " ? " is expressed as the angle of difference from the E W axis, and the formulas are flipped, i . e . the Difference of Latitude formula becomes the Departure, and the Departure formula is the Difference of Latitude ).
• The Moon's line of apses, i . e . the long axis of the Moon's orbit when approximated as an eccentric ellipse, rotates once in about nine years, so that it can be oriented at any angle whatever relative to the direction of the Sun at any season . ( The angular difference between these two directions used to be referred to, in much older literature, as the " annual argument of the Moon's apogee " . ) Twice in every period of just over a year, the direction of the Sun coincides with the direction of the long axis of the eccentric elliptical approximation of the Moon's orbit ( as projected on to the ecliptic ).
• In the aerodynamics of rotorcraft such as helicopters, "'phase lag "'refers to the angular difference between the point at which a control input to a rotor blade occurs and the point of maximum displacement of the blade in response to that control input, said displacement occurring in the direction of rotor rotation . " Phase lag " differs from " advance angle " in that the latter refers to the mechanically fixed angle between the pitch link attachments at the blade and swashplate . " Phase lag " can vary as a function on rotor tilt rate and aerodynamic damping and results in " cross-coupling " between the aircraft control axes; " advance angle " is fixed and cannot vary.
