Engineering Thermodynamics Complete lecture notes by Eng.D.L.Kumudu      Download - Click Here Thermodynamics and Energy Heat, energy, transformations, are all ways that thermodynamics is tied into society. Have you ever touched a piece of metal and a piece of wood in the same room? You noticed that the metal felt cooler than the wood, yet are they the same temperature? That is an example of thermodynamics. When your hand touches the metal, your hand releases heat through conductivity, or the ability to conduct heat or energy.When your hand touches the metal, it releases more heat than when your hand touches the wood. Even though the metal feels cooler, they are at the same temperature The concept of thermodynamics came into place when steam engines were becoming popular during the Industrial Revolution.Thermodynamics is the most present science in your life. In fact, it is so present in your da...

Engineering Graphics and AutoCAD lecture notes   Download - Click Here LOCUS It is a path traced out by a point moving  in a plane, in a particular manner, for one  cycle of operation. The Cycloid The cycloid is the locus of a point on the circumference of a circle as the circle rolls, without  slipping, along a straight line. The Involute There are several definitions for the involute, none being particularly easy to follow. An involute is the locus of a point, initially on a base circle, which moves so that its straight- line distance, along a tangent to the circle, to the tangential point of contact, is equal to the  distance along the arc of the circle from the initial point to the instant point of tangency. Alternatively, the involute is the locus of a point on a straight line when the straight line rolls  round the circumference of a circle without slipping. The involute is best visualised as the path traced out by the end of...

Senior Lecturer  Department of Surveying and Geodesy Faculty of Geomatics Sabaragamuwa University of Sri Lanka. 70140, Belihuloya. Branch of surveying in which both horizontal & vertical distances between stations are determined from instrumental observations (Agor, 1996). Uniqueness! No need of slope corrections, tension, etc... since no chaining involved. Rapid & convenient Good for rugged terrains with deep valleys, mountains, across water bodies... But low accuracy... Purpose; Preparation of contour plans with details. Widely used in preliminary site locating for railways, roads, canals, reservoirs, etc...
