You should get 97 degrees west of north, or 263 degrees, which is just slightly south of due west. ONC04 Mate of LT 500-1600 GRT Modules: Q139-Q142. Practice Problems for Kalamazoo Astrolabes. Calculate the satellite's altitude at perigee and apogee. Read off the degrees to the east (left) of North. you may need to add 360 to computations to facilitate subtraction. Local noon is when the sun is due south (nearest the throne if you hold the astrolabe correctly with the throne on the top). Starting with the azimuth of line AB. Including multiple parts, there are 600 problems in the text and solutions are presented here for the majority of them.

Requirement: Determine The dogleg severity at each inclination. Traditionally, the 'half-haversine' formula was used for this task but this formula does not lend itself well to solution by electronic calulator; therefore, the following solutions involve the cosine formula. Some problems will require answers using hand Azimuth: Quiz & Worksheet for Kids. problem set. b) Repeat the time corrections as above: Angles: To find the Angle between two Azimuths, subtract the smaller Azimuth from the larger Azimuth. 10:00 PM - (-16 min) + (-5 min) - 60 min = 10:00 + :16 - :05 - :60 = 9:11 PM The sun sets in the southwest on the winter solstice. Given the polygon shown in Figure 1 which is a part of a triangulation system.

Please use the purchase button to see the entire solution. d) Set astrolabe with sun's location (Aries 13) and rule lined up with 9:11 in the WEST. 7.8 N44°50 '38"E, S38°42 '54"E, S45°06 '02'W, and N13°24"30"W Course AB of a five-sided traverse runs due north. a gimbal with known misalignments) at its target. 7 X 4 = 28 min, so add 28 minutes to local solar time to reach clock time. add -12 minutes to local solar time to reach clock time. On the front line up Capricorn 1 with the western horizon line (on the right if the throne is on the top). FE Reference Handbook, NCEES, Fall 2009 2. First, move the branch point of the path involving HI outside the loop involving H,, as shown in Figure 3-43(a). For this example (normal faulting, azimuth E-W), an ideal fault would occur with a strike E-W and dip 60 (assuming ).This is the orientation of a plane with maximum .. advantages over the tilt-swing-azimuth system, but the tilt-swing-azimuth system is perhaps more easily under-stood. Practice Problems 1 Angles and Bearings.
