Question
Download Solution PDFTachometric formula for horizontal distance using inclined sights through θ is obtained by multiplying
Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFTachometer: It’s a transit theodolite fitted with a stadia diaphragm which gives both horizontal and vertical control with an accuracy of 1 in 1000.
Horizontal Distance (D) ⇒
Vertical distance (V) ⇒
Where,
k = multiplying constant, c = additive constant, s = staff intercept, and θ = angle of inclination of measurement
For given condition: (θ = 0°),
Assuming analltic lens i.e. k = 100 and c = 0
∴ Tachometric formula for horizontal distance using inclined sights through θ is obtained by multiplying the multiplying constant by cos2 θ and additive constant by cos θ.
