Solution:

QUESTION: 2

The radial offset at a distance X from the point of commencement of curve of radius R is given by

Solution:

QUESTION: 3

The shape of the vertical curve generally provided is

Solution:

QUESTION: 4

If L is the length of transition curve and R is the radius of circular curve, then the shift of the curve is directly proportional to

Solution:

QUESTION: 5

For a simple circular curve, which one of the following gives the correct relation between the radius, R and degree of curve D, for 20 m arc length?

Solution:

For 20 m arc R = 1145.9/D

for 30 m arc R = 1718.9/D

QUESTION: 6

Which of the following elements of a simple curve are correctly matched?

1. Tangent length ..... R tan Δ/2

2. Apex distance .... 2R sin Δ/2

3. Length of long chord.... 2 R cosec Δ/2

4. Mid-ordinate .... R ver sin Δ/2

(R is the radius and Δ is the deflection angle)

Select the correct answer using the codes given below:

Solution:

QUESTION: 7

If a tacheometer is fitted with an anallatic lens

Solution:

QUESTION: 8

If Δ is the angle of deflection of the curve, T_{1 }and T_{2} are its points of tangencies, the angle between the tangent at T_{1} and long chord T_{1} T_{2} will be

Solution:

QUESTION: 9

If R is the radius of the main curve, θ the angle of deflection, S the shift and L the length of the transition curve, then, total tangent length of the curve, is

Solution:

QUESTION: 10

If the intercept on a vertical staff is observed as 0.75 m from a tacheometer, the horizontal distance between tacheometer and staff station is

Solution:

Because additive constant is zero and multiplying constant is 100 for a tacheometer
