horizontal angle การใช้

• They also facilitate vertical and horizontal angles in otherwise straight pipelines.
• The horizontal angle of the rear machine gun field of fire was 100?
• However the camera's horizontal angle varies as the focal length of its lens changes.
• This caters for changes in shaft length and horizontal angle.
• The horizontal angle between two landmarks defines the circumcircle upon which the observer lies.
• Horizontal angle irons were attached to carry the ends of the floor and ceiling joists.
• Horizontal angles run anticlockwise from due front and vertical angles are positive above the horizontal, negative below.
• The ideal optimum viewing distance is affected by the horizontal angle of the camera capturing the image.
• The clay should always be on a common trajectory for height, even though it is variable in horizontal angle.
• By comparison, Cavalier can easily be identified by the vehicle's rear armour plate, which incorporates Crusader style horizontal angled exhaust louvres.
• For rough or approximate survey work, the ordinary method of measuring horizontal angles is used as it is less time consuming.
• Leonard Digges described a Theodolite that measured horizontal angles in his book " A geometric practice named Pantometria " ( 1571 ).
• The horizontal angles are 100 x 75 x 16 mm and secured with an additional 13 or 14 rivets per web plate.
• As the sheet is loosened to increase the horizontal angle of the boom and sail, the sheet becomes horizontal and exerts less downward force.
• Horizontal angles can vary from 0 degrees to 45 degrees either side of the centre line and target distance is between 60 and 70 metres.
• Intensity through various vertical and horizontal angles, intensity ratio between bright and dim modes of a park / turn or brake / tail lamp, etc.
• An alidade on the base was used to sight an object for horizontal angle measurement, and a second alidade was mounted on the vertical semicircle.
• "This is an attempt to vote for Al Gore, " board member Suzanne Gunzburger, a Democrat, said as she examined a ballot at a horizontal angle.
• With indirect fire the horizontal angle is relative to something, typically the gun's aiming point, although with modern electronic sights it may be a north-seeking gyro.
• Later instruments had a single alidade on the vertical semicircle and the entire semicircle was mounted so as to be used to indicate horizontal angles directly.
