Creep of Rail Creep of Rail is defined as a longitudional movement of rail with respect to sleeper. Rail have the tendency to gradually move in the direction of dominant traffic. The creep of rail is common to all railway tracks and its value varies from almost nothing in some cases to about 130 mm/ … Read more Creep of Rail : Causes, Effects and Prevention of Creep
What is Scale and Types of Scales in Surveying . A scale is the ratio of the distance marked on the plan to the corresponding distance on the ground. A good draughtsman can plot a length to accuracy within 0.25 mm. Types of Scales are generally classified as large, medium and small. There are generally … Read more Types of Scales in Surveying
Introduction to Surveying Surveying is the science and art of determining the relative positions of various points above, on or below the surface of the earth. The relative positions in surveying are determined by measuring horizontal distances, vertical distances (elevations}, horizontal angles and vertical angles accurately by using various surveying instruments. Important Objectives of Surveying … Read more Surveying : Introduction to the Concept of Surveying
