COMMON CURVES USED IN ENGINEERING PRACTICE

In engineering practice we see many objects having curved surfaces or edges. Every curve has a name and property which defines it. Point is the basic identity in a drawing. All curves are obtained by the path traced by a point while moving in a constrained motion. Most commonly used curves in engineering practice are 1.    Conic Sections: – These are the curves obtained on having sections of a right circular cone by a plane from different positions relative to the axis of cone. Circle, Ellipse, Parabola and Hyperbola are the curves defined by conic sections. 2.    Cycloidal Curves :-…

RAINWATER HARVESTING FOR BORE WELL RECHARGING

Water is an essential for all living organism. In fact no life is possible without water. Bore wells are the common source for water in rural as well as urban areas. In summers the water level decreases and at some water deficient areas, the bore wells give-up the supply and get dry. In our ecosystem the water cycle or hydrological cycle in which water carried out from lakes, oceans, rivers, ponds etc in the form of water vapors. These vapors forms cloud and again these clouds turn into rain and supply water. Thus rain water is the natural source of…
