Set back distance for gate and engineering civil service with solved example

Image
Every point on highway adequate sight distance will be available on a horizontal curve. In the horizontal curve is a location which could be the problem of side distance so adequate sight distance must be installed on a horizontal curve for safe and efficient movement of traffic. See problem of Sight distance on a horizontal curve because of obstruction at the inner is of horizontal curve. Seeing the image due to some buildings we are not able to see line AB. We are only able to see line AC so this is the obstruction at the horizontal curve.  Obstructions such as building trees, cutting slopes etc along the net are responsible.  On a narrow Road TV side distance is measured along the centre line of the road and on wider Road decide distance is measured along the centre line of the inner side line.  Setback distance depends on the value of the required side distance, radius of curvature and length of curve.  Generally two case are considered for analysis of setback distance Sight distan

Soil Acidity And Alkalinity UPSC Geography Optional

Image
In pedology we have to study the soil pedology. There are two segment of soil properties one is chemical and other one is physical and biological. In chemical the most important it is pH values. PH values deal with the amount of acidity or alkalinity in the soil. it's also indicate the quality of soil and its productivity. Getty image Soil acidity and alkalinity pH factor expresses soil properties. pH is best on relative concentration of of active hydrogen ions ( H+) . With increasing concentration the acidity will increases and pH value decreases.  Soil group Lotosols soils Brown forest soil Brown Podzols Podzols Prairies soil Chestnut soil Brown soil Lotosols means this soil is is a type of laterite where pH values is neutral. will going below the 7 acidity have more concentration and this type of soil called brown forest soil. Brown forest soil is more acidic than Lotosols. Acidity is more in the forest region because the plant and their leaves have more acidic more acidic chara

KARST TOPOGRAPHY UPSC

  LIMESTONE AREA IS CALLED KARST AREA. IT IS FOUND IN FOLDED MOUNTAIN, KARST AREA IS LOCATED IN DINARIK ALPS IN WEST YUGOSLAVIA.  BESIDES IT KARST AREA IS FOUND OVER ROCKIS, ANDES HIMALAYA etc.  MOST COMPLEX AND INTERLOCKED CAVES ARE FOUND IN PAMIR REGION. SCIENTIFIC STUDY OF CAVE IS CALLED SPELEOLOGY. KRAS(SLAVIC) CARSO[ITALIAN] KARST PROCESSES ÇAUSSES (FRENCH 1. SOLUTION OR CARBONATION  DUE TO PRESENT OF VARIOUS GASSES AND ACID IN WATER, IT ACT AS A IMPORTANT SOLVENT. IT MAY NOT BE EFFECTIVE FOR ALL ROCKS BUT WHEN IT'S COME TO CONTACT WITH LIME STONE, DOLOMITES OR CLACK IT BECOME MOST POWER FULL AGENT OF EROSION.  2. HYDRAULIC ACTION DUE TO ENORMOUS FORCES IN RUNNING WATER IT STRIKE STREAM BED ON ITS BANK. IT MAY LOOSEN THE ROCKS, LIFT IT AND EASILY TRANSPORT IT.  3. CORRASION OR ABRASION  DAMAGE TO A SURFACE CAUSED BY RUNNING SOMETHING VERY HARD AGAINST IT. RUNNING WATER WHEN RUBBED WITH SAND, SILT AND OTHER SEDIMENTS ACTS AS VERY EFFECTIVE MEANS OF EROSION OF THE RIVER BED. IN

Geological formation of India

Image
 Today we are going to learn  about the geological formation of India.  Image credit - Getty image Geological formation of India Distribution of igneous, metamorphic and sedimentary rocks is the result of the following geological events in India. The distribution of Rocks in different places give the idea of the formation of India.  History of geological formation of India Cooling and Solidification of the crust surface ( plateau region) in the pre-cambrian era ( prior to 600 Million years ago). Archaean Gneisses and granites were formed, rocks were Metamorphosed, minor igneous activities occurred, Araveli folded mountain come into existence.  After this leveling of the insulations and crushing or crumbling of the sediments of the Dharwarian group in Bijawars occurred.  Calcareous deposits corresponding to humid and semi-arid climatic regims in the cuddapah(also know as kadapa) and Vindhayas basin are founded and its uplift during Cambrian period ( 500 Million years ago).  In the Permo

Soil moisture - Water added to a soil during irrigation is held in the pores of soil and this is termed as soil moisture.  Basic physical properties of soil Soil provides necessary medium for water to be used by plants through their roots. Water acts as a medium to carry a large amount of nutrients essential for growth of a plant. The rate of entry of water into the soil, it's retention and then its movement and availability of plant roots are physical phenomena that contribute to the growth of vegetation.  Classification of soil water Gravitational water Capillary water Hygroscopic water Gravitational water is not held by soil and drains freely under the influence of gravity.  Capillary water is held in the soil or retained in the soil after the gravitational water has drained off. The capillary water was also designated as available water.   Hygroscopic water it is that water which is absorbed by the particles of dry soil from the atmosphere and is held as a very thin film on the

What is stopping sight distance - some popular example

Image
Sight distance - when we move on the road then how much visible length available on the road is called sight distance. It is the total distance available on the road not perpendicular distance. Perpendicular distance available on road between user and object is called line of sight (LOS).  Type of sight distance SSD = Stopping Sight Distance OSD = overtaking Sight Distance ISD = Intermediate Sight Distance HSD= HeadLight Sight Distance Let's understand what is stopping sight distance Stopping sight distance = It is a minimum distance or available distance on the road to stop the vehicle safely without any collision is called SSD. We also called non passing sight distance and people also called absolute minimum sight distance or head light sight distance.  In the above image you have seen, stopping sight distance is the sum of leg distance plus braking distance.  Leg distance Braking Distance So equation of SSD is  SSD = V×t + V×V/2gfb b = is breaking efficiency When a vehicle is m

What is the camber? - How does camber impact alignment

Image
Camber - when we rise the road about the center line for proper drainage then the rise height is called camber height. For different types of camber central height remains the same.  There are many types of camber such as straight line camber, parabolic camber and also combination of straight line and parabolic camber.  Straight line camber Parabolic camber In the above images you have seen straight and parabolic camber and also the equation of camber height.  Let take an example Provide 3 percent camber and the road is 4 lane then find the equation of parabolic camber.  Solution 4 lane road than width of the road is = 3.5×4 = 14 1/n = 3/100  Some recommendations of IRC for camber height in different terrain We can't provide high camber because it can harm the pavement material due to high velocity of water.  For mixed traffic conditions we generally prefer mixed camber. 

why rbi prints limited currency

The government and RBI should work in maintaining the balance between production and currency rotation in the hands of people. So, printing money can't be solution to raise the economy. When you have more money and less things to buy, then the money will lose its importance. Can RBI print unlimited currency?

However, if the Reserve Bank wants to print anything higher, the government must amend the Reserve Bank of India Act. ... (For related reading, see: India Discontinues 500 and 1000 Rupee Currency Notes.) On what basis does RBI prints currency? Printing of currency notes in India is done on the basis of Minimum Reserve System (MRS). This system is applicable in India since 1956. According to this system, the Reserve Bank of India has to maintain assets of at least 200 crore rupees all the times. Why can't countries just print more money? If governments print m
