Solutions
S1. Ans.(b)
Sol. in geodetic survey curvature of the earth is considered.
S2. Ans.(c)
Sol. In well condition triangle angle should be in range of 30° to 120°
S3. Ans.(b)
Sol. True length of chain (L) = 30 m.
False length of chain () = 29.9 m.
False length of chain () = 300 m.
True length of chain (l) = ?
L×l=L^1×l^1
30×l=29.9×300
l=(29.9×300)/30
▭(l=299m)
S4. Ans.(d)
Sol. surveyor compass work’s on the principle of quadrilateral bearing system. In quadrilateral bearing system 0° denoted at true north & true south . degree is 90° denoted at East or West
S5. Ans.(c)
Sol. the surface parallel to earth surface in known as level surface. And tangent to any point of level surface is horizontal surface.
S6. Ans.(b)
Sol. Plane table survey instruments –
(i) Plane table board
(ii) Alidade
(iii) Plumb bob & plumb fork
(iv) Compass
(v) Spirit level
(vi) Chain
(vii) Ranging rod
(viii) Tripod
(ix) Drawing sheet
S7. Ans.(a)
Sol. closed contour higher value inward represent ‘Hill’
S8. Ans.(a)
Sol. Hydrographic survey deals with the large water bodied like river canal, lake, sea etc.
Hydrographic survey is the science of measurement of features of marine construction.
S9. Ans.(b)
S10. Ans.(d)
