Give me the Explanation.

Kaushik Das said: (Oct 6, 2017)  
How?

Amal Zad Khan said: (Dec 2, 2017)  
Please explain it.

Nayan said: (Dec 18, 2017)  
Correction is = 100(sec a-1).

Md Shekhar said: (Dec 21, 2017)  
Slope correction=h^2/2L;
where h=L*angle in radian(a),
Here L=100 links,
So, slope correction=100*a^2.

@Md Shekhar.

Then it will be 50a^2, right?

Garry said: (Jan 7, 2018)  
Agree @ Deepa.

The answer should be 50 a^2.

Er Bibek said: (Apr 5, 2018)  
I agree on @Garry and @Deepa.

It should be 50a^2.

100a^2÷2 = 50a^2.

ch= s(1-cosθ)
ch= s- s cosθ
ch= s - d
Because d= s. cosθ.

For example: s=100, slope angle 45 degree
d= 100 . 0.70710
d= 70.71 THIS IS THE CORRECTION OF SLOPE LENGTH.

ch= 100-70.71.
ch= 29.29.
Ch is the correction of measured slope distance due to slope;
d is the horizontal distance.

@Sameer Sopori.

Please explain how come 100 α?

Sajith Ca said: (Dec 1, 2018)  
Please explain the answer.

Biswajit Koley said: (Feb 6, 2019)  
Some book answered it 1.5a^2/100.

How it's come please explain?

Shaa said: (Oct 16, 2019)  
@Biswajit Kiley. Your answer is correct for slope in degree. Here slope in radian.

Blaski said: (Feb 4, 2020)  
In degree : (1.5a^2)/100.
In radian : 100a.

Kashyap said: (Feb 12, 2020)  
Please give me the correct answer.

Rupesh Kumar Verma said: (Jun 27, 2020)  
Given data
Chain length:- 100 links
The slope of angle is (α) degree.

Correction for length is given as:-
Correction:- Chain length * Angle if Slope.

So, correction = 100 * α.

So, B is the correct answer.

How? anyone explain.

Kartik said: (Sep 6, 2020)  
@Blaski.

Please explain me the solution.
