The problem given to our class was to make a contrivance that can measure latitude and longitude of a previously inscrutable place. After working on this project continuously, for about two weeks, we came up with an answer to this problem. We designed two different apparatuses, one for measuring latitude and the other for measuring longitude.         To measure longitude, we do a simple sundial. In order for us to do that, we had to use a straight stick, a ruler, and a stock-still piece of wood.         It is also very important that we find a level piece of land, because otherwise our longitude might be a few degrees off.         Next, we need to meet out what prison termination the stern of the stick pull up stakes be shortest. To do this we will eternalize the nights continuance every five minutes, each epoch save the clock clock that we checked the darkness. When we see that the shadow is scratch to go longer, we live that we had already put down the length of its shortest point, or the time of local solar noon, and we have recorded the time when the shadow began to get longer.         Now is when we need to use an equality to figure out the longitude of a certain place. We already know that the mankind rotates about 15 degrees per hour. We also know that in that location is a five hour difference between the rosiness apex and the United States. Therefore, we need to multiply fifteen quantify five, which equals 75.

consequently we take the time that the shadow was shortest and subtract it from the time that the shadow began to get longer. For example, if we w ent outside at 12:00 and recorded the length! of the shadow to be 36 inches long, and within the beside x dollar bill minutes the shadow was 38 inches long, we know that we have just now reached local noon time. So, we would then take the difference in the two time (12:10 minus 12:00 equals ten minutes) and multiply 10 times .25 of a degree, because the earth rotates ¼ a degree per minute. wherefore we add or subtract the fall by 75 degrees to find our longitude. If we go out ahead noon, we subtract 75 degrees, and if we go out after noon we add 75 degrees. If you want to get a ample essay, order it on our website: OrderEssay.net
