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.
