Other (s) Estimating Problem There are a number of methods that can be used to estimate the height of Bell's tower as shown in Figure 1. One of the most accurate estimation methods that can be used involves calculating the height using the formula: Height of the tower= Number of stories x Average floor-to-floor height. Generally, this method of height estimation is based on the assumption that the floor-to-floor height of a building such as a church is 3.5m (Gibson, 67). The Shrines bell tower is located on the 8th story and therefore the approximate height of the Bell tower can be given as H=8 x3.
5 meters above the ground. The accuracy of this method is approximated to be +2.5 or -2.5 meters. 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 Shrine's doors can be arranged to reach the bell tower and then multiply our results by the average height of the 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= is 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, the 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 meter. The average weight of concrete per cubic meter is 2400 kg. Each story can be approximated to be 3 x 3 x10= 90m3. there are 8 floors each 3 x 3=72m3. =(90 x6)m3 + 72m3=540+72.Approximate weight of the building=(612m3 x 2400)Kg =1843.344Tons Total load exerted on the foundation=(1843.344 x10)N=1, 8433 N..
