Estimating - Essay Example The accuracy of this method is approximated to be +2.5 or -2.5meters. Another method that can potentially be used is by comparing the picture of the Shrine with an object (in the same picture) whose height is known. For example, we can calculate the number of repeated times through which the Shrines doors can be arranged to reach the bell tower and then multiply our results by the average height of Shrine’s door. An average of 11 doors can fit into the Bells height and each door is approximated to be 3m tall. This means that the approximate height of the Shrines bell= 11 x3=33 meters above the ground. Lastly the height of the Bell can also be estimated using simple Trigonometry. Using a position with a known distance from the Shrine building, the height of the location of the Shrines tower can be calculated as Height=Tan (Angle) x the known distance. The accuracy of this method is often =0.5 or -0.5. In my opinion, trigonometry method is better than the other methods since it has minimal error. The total load exerted by the bell tower can be estimated using the formula Total load= load per floor x the number of stories. Since the bell tower is entirely constructed using concrete, the weight of the walls and floors can be estimated as W= area of floors and walls x average weight per squire meters. The average weight of concrete per cubic meters=2400kg. Each story can be approximated to be 3 x 3 x10= 90m3. there are 8 floors each 3 x 3=72m3. =(90 x6)m3 +
