Question

What is two-point problem? How is it solved?

Answer 1

Answer:

Definition of two-point problem

: a problem in plane-tabling in which two points are mapped on the paper and a third is occupied on the ground to do which a fourth point is occupied temporarily

Explanation:

In this problem, two well-defined points whose position has already been plotted on the plan are selected. Then by perfectly bisecting this point a new station establish at the required position.

Procedure-

Procedure-Suppose P and Q are two well-defined points whose position are plotted on the map as P and Q. it is required to locate a new station at A by perfectly bisecting P and Q.

Procedure-Suppose P and Q are two well-defined points whose position are plotted on the map as P and Q. it is required to locate a new station at A by perfectly bisecting P and Q.An auxiliary station B is selected at a suitable position. The table is set up at B. and levelled and oriented by eye estimate. It is then clamped

Procedure-Suppose P and Q are two well-defined points whose position are plotted on the map as P and Q. it is required to locate a new station at A by perfectly bisecting P and Q.An auxiliary station B is selected at a suitable position. The table is set up at B. and levelled and oriented by eye estimate. It is then clampedWith the alidade touching p and q. the point P and Q bisect and rays are drawn. Suppose this ray intersect at b.

Suppose this ray intersect at b.With the alidade centre on b, the ranging rod at A is bisected and ray is drawn. Then the eye estimation the point a1 is marked on this ray.

Then the eye estimation the point a1 is marked on this ray.The table is shifted and centre on A with a1 just over A. it is levelled and oriented by Backsight. With the alidade touching P, the point P is bisected and ray is drawn. Suppose this ray intersect a line ba1 and a1 as was assumed previously.
