MSTE EVAL EXAM 4 SOLUTIONS ▣ 1. Shown is the figure From setup 1, h + 0.75 + e = 2.766 + e h = 2.016 m From setup 2, e1 25 = e2 230 → e2 = 9.2e1 h + 1.906 + e1 = 3.789 + e2 2.016 + 1.906 + e1 = 3.789 + 9.2e1 e1 = 0.01622 m Therefore, the reading at P at setup 2 is: 1.906 + 0.01622 = 1.922 m ▣ 2. Note that for the elevation between two points, Elev2 = Elev1 +∑(BS − FS) The total back sights from BM1 to TP3 is ∑BS = 7.69 While that of the foresights, ∑FS = 13.097 The elevation of BM4 is BM4 = 127.133 + 7.69 − 13.097 BM4 = 121.726
