3 SECTION B : 50 MARKS BAHAGIAN B : 50 MARKAH INSTRUCTION: This section consists of FOUR (4) essay questions. Answer TWO (2) questions only. ARAHAN: Bahagian ini mengandungi FOUR (4) soalan esei. Jawab DUA (2) soalan sahaja. QUESTION 1 SOALAN 1 (a) Tachymetry is used to determine the elevation of the reduce level at station 2 based on elevation of station 1. Explain the tachymetry stadia formula below by using illustrations. Tekimetri digunakan untuk menentukan ketinggian alat di stesen 2 berdasarkan ketinggian stesen 1. Terangkan formula tekimetri dibawah dengan menggunakan ilustrasi. R.L. STN 2 = R.L. STN 1 + H.I + V h Where: R.L. STN 1 = Reduced Level of instrument station 1 R.L. STN 2 = Reduced Level of instrument station 2 h.i = Instrument height h = Middle stadia V = Vertical distance 4 SULIT

4 Dimana : R.L. B = R.L. A + H.I + V h A.L. STN 1 = Aras laras distesen 1 R.L. STN 2 = Aras laras distesen 2 h.i. = Ketinggian Alat h = Stadia tengah V = Jarak pugak (b) The following is tachymetry data from station 1 to staff 2 and from station 1 to staff 3 with multiplying and additive constant are given as 100 and zero. The distance from staff 2 to staff 3 was measured as 157m. Compute the horizontal distance and vertical distance for station 1 to staff 2. Station Staff Staff Readings (m) Vertical Angle Below Middle Upper [6 marks] Berikut adalah data cerapan tekimetri dari stesen 1 ke staf 2 dan dari stesen 1 ke staf 3 dengan pemalar darab dan pemalar tambahan ialah100 dan 0. Jarak staf 2 ke staf 3 yang diukur ialah 157m. Hitung jarak yang mendatar dan jarak pugak untuk stesen 1 ke staf 2. Stesen Staf Bacaan staf (m) Sudut Pugak Bawah Tengah Atas [6 markah] 5 SULIT
