## What is a level line?

A level line is the distance between 2 points on the level surface, which follows the curvature of the earth.

Whereas the line of sight is the straight line perpendicular to the plumb line at the telescope..

## What is horizontal surface?

Noun. 1. horizontal surface – a flat surface at right angles to a plumb line; “park the car on the level” level. floor, flooring – the inside lower horizontal surface (as of a room, hallway, tent, or other structure); “they needed rugs to cover the bare floors”; “we spread our sleeping bags on the dry floor of the tent …

## What is block contouring?

Contouring in surveying is the determination of elevation of various points on the ground and fixing these points of same horizontal positions in the contour map.

## Which line is the tangential to the level line at a point?

7. Which line is the tangential to the level line at a point? Explanation: It is straight line tangential to the level line at a point. It is also perpendicular to the plumb line.

## Who uses plumb line?

The instrument has been used since at least the time of ancient Egypt to ensure that constructions are “plumb”, or vertical. It is also used in surveying, to establish the nadir with respect to gravity of a point in space.

## What is the time that is normal to plumb line at all points?

▶A line normal to the plumb line at all points is known as “Horizontal Plane”.

## What is the surface that is normal to the direction of gravity at all points?

Discussion :: UPSC Civil Service Exam Questions – Section 10 (Q. No. 23)[A].A horizontal surface every element of which is normal to plumb line[C].A plane surface which is perpendicular at all points to the direction of gravity[D].A curved surface which is perpendicular to the direction of gravity at every point1 more row

## What is a plumb line for wallpaper?

Your first wall plumb line will be a guide for aligning the first strip of wall coverings you put up. Strike the plumb line a wall covering strip’s width minus one-half inch from the doorway starting point. Each time you turn a corner, create a new plumb line to get a fresh alignment.

## Which of the following Levelling is carried out to determine the elevation difference between two points on the surface of Earth?

Barometric levellingExplanation: Barometric levelling make use of the phenomenon that difference in elevation between two points is proportional to the difference in atmospheric pressure at these points.

## What is the length of ranging rod commonly used?

The rods are usually about 30 mm in diameter and 2 m or 3 m long, painted with alternating bands, such as red and white, red and yellow, or black and white, in lengths of 200 mm (i.e. one link length of metric chain), 500 mm, or one foot.

## What is the difference between a level surface and a horizontal surface?

Level surface : A surface which at every point is perpendicular to a plumb line or the direction in which gravity acts; parallel to the surface of still water. Horizontal surface: A flat surface at right angles to a plumb line.

## Which branch of surveying is used to find the elevation of given point with respect to given or assumed datum?

levellingThe branch of surveying which deals with the determination of elevations of points or establishing the points at known elevation with respect to a given or assumed datum is known as levelling. Levelling is generally applied for the following civil engineering works: 1.

## What is the meaning of plumb line?

A plumb line is a weight suspended from a string used as a vertical reference line to ensure a structure is centered. … God’s plumb line “has a lot to do with the poor. It has a lot to do with righteousness that is living in right relationship with God and neighbor.

## What is level surface?

For a function of three variables, a level set is a surface in three-dimensional space that we will call a level surface. For a constant value c in the range of f(x,y,z), the level surface of f is the implicit surface given by the graph of c=f(x,y,z).

## What is a plumb line in anatomy?

The plumb line is a spatial term that places the body or bodies in relationship to the ground below. In proper anatomical position the joints would line up with a straight plumb line to the floor. … A plumb line between two bodies.
