MAPÚA INSTITUTE OF TECHNOLOGY Muralla St. Intramuros, Manila School of Civil, Environmental and Geological Engineering FIELD WORK NO. 8 DETERMINATION OF THE HEIGHT OF A REMOTE POINT COURSE AND SECTION: CE 120-0F/B7 SUBMITTED BY: SN: NAME: Pineda, Jose Jeffrey Zoilo F. GROUP NO: 7 STUDENT NUMBER: 2014100720 CHIEF OF PARTY: Pineda, Jose Jeffrey Zoilo F. DATE OF FIELDWORK: February 18, 2016 DATE OF SUBMISSION: February 22, 2016 SUBMITTED TO: GRADE PROFESSOR: ENGR. BIENVENIDO CERVANTES FINAL DATA SHEET FIELD WORK 8 (DETERMINATION OF THE HEIGHT OF THE MAPUA ADMIN BUILDING) DATE: February 18, 2016 TIME: 12 P.M. – 4:30 P.M. WEATHER: Sunny GROUP NO. 7 LOCATION: Intramuros wall PROFESSOR: Engr. Cervantes Where: H.I. = 1.5m H.D. = 14.80m Θ = 50○00” x = partial height of the building y = total height of the building Computation: Tan Θ = x_ H.D Tan 50○ = x___ 14.8m x = 17.63m Solve for y y = total height of MIT admin building y = x + H.I. y = 17.63m + 1.5m y = 19.14m The total height of the MIT admin building is 19.14 meters. CONCLUSION Trigonometry is very useful in determining the unknown side of a specific triangle. In this field work activity, the concept of the right triangle in trigonometry is very well used. In determining the height of the Mapua admin building, we are able to master the reading of the vertical angle using the theodolite. Also, in this field work activity, we are able to apply the knowledge learned in the analysis of right triangles in determining the height of a remote point. Trigonometry doesn’t end in passing the Trigonometry subject and we will use it always in our engineering careers. RECOMMENDATIONS The field work is very easy and very short. But always remember the basics of surveying and do not rush the activity because you might repeat the field work if you didn’t get the correct data because of rushing. Some pictures during the field work. The picture on the left shows the group is setting up the instrument (Theodolite). The picture on the right shows the group setting up the theodolite and aligning its view to the top of the flag pole. The picture on the left shows the instrument man getting the vertical angle from his position to the top of the flagpole.
