Theodolite surveying
                                       A theodolite surveying is the most precise instrument designed for the measurement of horizontal and vertical angles and has wide applicability in surveying such as

a) laying off horizontal lines
b) locating points on line
c) prolonging survey line
d) establishing grades
e) setting out curves etc

A theodolite may be tranist theodolite in which the line of sight can be reversed by revolving the telescope through 180°, in the vertical plane . The theodolite in which the telescope can not be transited are known as non transit theodolite.

Grade of concrete

Grade of concrete                                   Grade of concrete is defined as the minimum strength the concrete must possess after 28 days of construction with proper quality control. Concrete grade Grade                  Proportion  M 5.                      1: 5 : 10          M7.5.                    1 : 4 : 8        M10                      1 : 3 : 6    M15.                    1 : 2 : 4    M20.                    1 : 1.5 : 3    M25.                    1 : 1 : 2    M30                      1 : 0.75 : 1.5

10 class math airthmatic progessions excerise 5.1

Excerise no 5.1 1) In which of the following situations, does the list of number involved makes as airthmatic progessions and why ?   A) the taxi fare after each km when the fare is RS 15 for the first km and RS 8 for each additional km  Answer    It can be observed that  Taxi fare for 1st km = 15   Taxi fare for first 2nd km = 15+8 = 23 taki fare for first 3rd km  = 23+8 = 31 Taki fare for first 4 km    =31+8 = 39 Clearly 15, 23, 31, 39 form an A.P. because every term is 8 more than preceding term. B) the amount of air present in the cylinder when a vaccum pump remove 1/4 À of the air remaining in the cylinder at a time Answer  Let the initial volume of air in a cylinder by V litres . In each stock the vaccum pump remove À 1/4 À of air remaining in the cylinder at a time . In other words after every Stoke only 1- 1/4 = 3/4 Part of air will remain Therefore volume will be V, 3V/4 , (3V/4 )², (3V/4 )³.... Clearly it can be observed tha

Spread Foundation or open Foundation The Foundation which is constructed over a large area to form a wide base over which the whole structure rests is called spread or open Foundation. These Foundations are made with increasing the base by making off sets. It is a type of shallow Foundation. this type of Foundation is constructed in open excavation by increasing the area at the base of structure by means of offsets or batter. This is most common type of Foundation and is practicable for a depth of about 5 m and is generally convenient above the water table. This Foundation is provided for bridges of moderate height built on sufficiently firm dry ground. If the ground is not stiff the bearing surface is further extended by wide layers of line concrete at the bottom. Method of construction                                             Excavate the Foundation trench to the exact width and to the designed depth. the bottom is well rammed and then Foundation lime concrete in layers
