What is Theodolite, Uses of Theodolite and types of Theodolite

What is Theodolite

Theodolite is the instrument which is mainly used for taking horizontal and vertical angle up to 10" or 20" depending upon the least count of the instrument.

Uses of Theodolite

There are many uses of Theodolite, the following are the different purposes for which the theodolite can be used..

1. Measuring Horizontal Angle

2. Measuring Vertical Angle

3. Measuring Deflection Angle

4. Measuring Magnetic Bearing

5. Measuring Horizontal distance between two points

6. Finding Vertical Height of an object

7. Finding the different of elevation between various points

8. Ranging a Line

How many Types of Theodolite

Theodolite may be of two types

1. Transit Theodolite

2. Non - Transit Theodolite

Transit Theodolite :- In Transit Theodolite, the telescope can be revolved through a complete revolution about its horizontal axis in a vertical plane

Non - Transit Theodolite :- In Non - Transit Theodolite, the telescope can be revolved through a complete revolution in the vertical plane But it can revolved to a certain extent in a vertical plane, in order to measure the angle of elevation or depression.

What is Transiting of a Theodolite

The method of turning the telescope about its horizontal axis in a vertical plane through 180° is termed as transiting .

What is Swinging The Telescope

This indicates turning of the telescope in a horizontal plane . It is called right swing when the telescope is turned clockwise and left swing when the telescope is turned anticlockwise

What is axis of the telescope

The axis of the telescope is the imaginary line passing through the optical centre of the object glass and the optical centre of the eyepiece

Surveying in Engineering

Surveying in Engineering By S. Islam - 10 jul 2020 Surveying is the most important part in Civil engineering as well as Construction Engineering. Without Surveying we can't start a construction such as road , railways , irrigation, canals , bridge etc . Content 1. Definition of Surveying in Civil Engineering . 2. What is Levelling . 3. Uses of Surveying . 4. Classification of Surveying . 5. General principle of Surveying . SURVEYING :- Surveying is the art of dermining the relative position of different object on the surface of the earth.By measuring the horizontal distance between them and preparing a map to any suitable scale thus in this discipline the measurement are taken only in the horizontal plane . Or We can say Surveying is nothing but data collection . Lvelling :- Levelling is the art of dermining the relative vertical point on the surface of the earth , in the case of levelling the measurement are taken only

Navigating the Bend: The Art and Science of Curve Setting for Roads and Railways

Navigating the Bend: The Art and Science of Curve Setting for Roads and Railways Introduction The world of transportation infrastructure is a complex tapestry woven from the threads of engineering, physics, and design. While we often take smooth and safe journeys along roads and railways for granted, the science behind those gentle curves that keep us on track is both fascinating and crucial. Welcome to the realm of curve setting, a meticulous process that blends art and science to ensure efficient, safe, and comfortable transitions in transportation infrastructure. The Basics of Curve Setting Curve setting is the strategic design of curves along roads and railway tracks, aimed at facilitating seamless transitions from straight segments to curves. These curves are essential in maintaining the harmony of speed, comfort, and safety. Radius of Curvature: Central to curve setting is the concept of the radius of curvature. This refers to the radius of the circle that best fits the curve.

What is Topographic Survey , The Importance of Topographic Surveys . How is a Topographic Survey Conducted?

Introduction In the world of land development, construction, and infrastructure planning, there exists a hidden hero that plays a crucial role in shaping our physical environment – the topographic survey. Often overlooked by the untrained eye, a topographic survey is an essential tool that empowers engineers, architects, urban planners, and various other professionals to make informed decisions when it comes to designing, building, and managing our cities and landscapes. In this blog post, we'll delve into the world of topographic surveys, understanding what they are, why they matter, and how they are conducted. What is a Topographic Survey ? At its core, a topographic survey is a detailed representation of the physical features of a piece of land or area. Unlike traditional maps that only depict the horizontal positions of objects, a topographic survey goes beyond, providing a three-dimensional visualization of the land's surface and the natural and man-made features that inh
