Determinate structure Indeterminate structure 1. When all forces in a structure is determined from equilibrium equations, the structure is known as statically determinate. When the unknown forces in a structure are more than the available equilibrium equations, that structure is known as statically indeterminate structure. 2. Support will not develop...

Name of Boundary Line In Between Countries Durand Line The Durand Line was a frontier boundary between Afghanistan and British India. It was established after an 1897 memorandum of understanding (MoU) between Mortimer Durand of British India and Afghan Amir Abdur Rahman Khan. Radcliffe Line On 17th August 1947 the Radcliffe Line was declared as the...
Layer Height(km) Features Troposphere 0-18km It Contains 75% of the gases in the atmosphere. As the height increases temperature decreases. Stratosphere 18-50km This layer contains the ozone layer. The temperature remains fairly constant i.e. -60 degree C. Mesosphere 50-80km Coldest region of the atmosphere, here temperature drops to about -100...

DETERMINATION OF MOISTURE (WATER) CONTENT(W) IN SOIL BY USING OVEN DRY METHOD Objective Determine the natural moisture content of the soil sample. Definition:-It is the ratio of the weight of the water to the weight of solids in soil mass and it is generally expressed in percentage and usually done...
S.No. Line of Collimation or HI method Rise and fall method Rise and fall method 1 It is more rapid and saves a considerable time and labour. It is laborious as the staff reading of each station is compared, to get a rise or fall. 2 It is well adopted...
Primary divisions of surveying are: Plane Surveying Geodetic Surveying Plane Surveying Geodetic Surveying The surveying in which earth surface is considered as plane surface. The surveying in which curvature/surface of the the earth is considered as curved surface. Earth’s curvature is ignored. Earth’s curvature is considered. The line joining any...
Tests used to find out Workability of a freshly mixed concrete are: Slump cone test Vee bee test Compaction factor test Slump test is performed on freshly mixed concrete to find out the water content and workability or consistency of concrete. The test is useful in controlling quality of the...
Under Reamed Pile These piles have one or more bulbs at its lower end. If the bulb is provided lower than the critical depth of moisture movement in expansive soils, the foundation will anchored to the ground and it would not move with the swelling and shrinkage of soil. They...
Compressive Strength of bricks is the load bearing capacity before it ruptures, when subjected to compressive stress. Hard and well burnt bricks have more compressive strength than the porous bricks. The crushing strength is the important factor for bricks, because it decides the suitability of brick for different uses. The...
Acne is a common skin condition that affects millions of people worldwide. It occurs when hair follicles become clogged with oil, dead skin cells, and bacteria, leading to the formation of pimples, blackheads, whiteheads, and sometimes even cysts. While acne is most commonly associated with adolescence, it can affect individuals...
