Measurement of Horizontal and Vertical Angles in Theodolite . The objective lens has to be focused whenever an object is sighted, as this depends upon the distance between the instrument and the object.

wooden block and the wooden surface of a horizontal and inclined plane will be derived and measured. By graphing these data, coecients of static and kinetic friction will be obtained. As you perform this experiment, theoretical quanti-ties will be determined prior to measuring for Part 2 through Part 5. These calculations will require the free-body diagram solution method (refer to Page 28 A basic modern optical theodolite typically consists of a small telescope which is connected to two angle measuring mechanisms, one for measuring horizontal angles and one for measuring vertical angles. It sits atop a rotatable base with a leveling mechanism on a tripod. Once the theodolite is set up, the telescope is turned to spot the desired point and then the angle from the point that the

### MEASUREMENT OF HORIZONTAL ANGLES BY REPETITION CE211 Fall 2011 Lab 5 Horizontal Angle Measurements Using. Horizontal angles are measured on the horizontal plane and establish the azimuth of each survey measurement. An azimuth is a horizontal angle measured clockwise from a Reflector­less Total Station Measurements and their Measures horizontal and vertical angles and slope distance from which horizontal distance is calculated. Given a known (or arbitrary coordinate), and a bearing, from which to start,. Measuring horizontal angles by repetition (digital theodolite) More reliable reading of angle value is made by repeating the measurement. The first angle is taken from BS to FS and written into field book.

ADVANCED SURVEYING TRIANGULATION Prof. UjjvalJ. Solanki, -net.pdf. Strength of figures The strength of figure is a factor to be considered in establishing a triangulation system to maintain the computations within a desired degree of precision. For a given change in the angles, the sine of small angles change more rapidly than those of large angles. This suggests that smaller angles less MEASUREMENT OF VERTICAL ANGLES: Vertical Angle : A vertical angle is an angle between the inclined line of sight and the horizontal.

Each … Method of Repetition in Theodolite In the method of repetition, the horizontal angle is measured a number of times and the average value is taken. It is usual to limit the number of repetitions to three with each face except in the case of very precise work.

A repetition is a single observation (in a series of observations) of a horizontal angle, made with a repeating theodolite. This type of theodolite is rarely used nowadays. Information about repeating theodolites can be found in surveying textbooks. Measurement of Horizontal and Vertical Angles in Theodolite . The objective lens has to be focused whenever an object is sighted, as this depends upon the distance between the instrument and the object.
