What is an lsometric drawing?
An isometric drawing is a schematic detailing a three-dimensional object in an abstract space that has no vanishing point. So, you can see the thickness of the object, but all sides remain parallel, unlike how objects appear in real life. In real life, the sides of an object converge as they get farther and farther from the eye. Think of a building whose sides slope into a point off in the distant horizon. These drawings are helpful in giving precise measurements, scale, placement and proportions. A good example of an isometric drawing would be the assembly instructions that come with a piece of household furniture.
What is a pictorial view?
A view of an object (actual or imagined) as it would be seen by an observer who looks at the object either in a chosen direction or from a selected point of view. Pictorial sketches often are more readily made and more clearly understood than are front, top, and side views of an object. Pictorial drawings, either sketched http://www.answers.com/topic/freehand or made with drawing instruments, are frequently used by engineers and architects to convey ideas to their assistants and clients. See alsohttp://www.answers.com/topic/geometry; http://www.answers.com/topic/engineering-drawing. In making a pictorial drawing, the viewing direction that shows the object and its details to the best advantage is chosen. The resultant drawing is http://www.answers.com/topic/orthographic if the viewing rays are considered as parallel, or perspective if the rays are considered as meeting at the eye of the observer. Perspective drawings provide the most realistic, and usually the most pleasing, likeness when compared with other types of pictorial views. Several types of nonperspective pictorial views can be sketched, or drawn with instruments. In the http://www.answers.com/topic/isometric pictorial, the direction of its axes and all measurements along these axes are made with one scale (Fig. 1). Oblique pictorial drawings, while not true orthographic views, offer a convenient method for drawing circles and other curves in their true shape (Fig. 2).Isometric drawing; measurements along each axis are made with the same scale.Oblique pictorial drawing. In order to reduce the http://www.answers.com/topic/distortion in an http://www.answers.com/topic/oblique drawing, measurements along the receding axis may be foreshortened. When they are halved, the method is called cabinet drawing.
What is sectional drawing?
A drawing that divides a cube, for example to see what's inside in it.
What is voltage harmonic?
In AC current, its a quality measurement of voltage. If voltage is harmonious or "clean" you will see an equal wave length on both sides of your baseline. You can test and see this using an electrical scope.
What is open delta connection in three phase transformer?
When you see "Delta" it is a kind of winding used in transformers or motors Think of a triangle. Each leg of the triangle is a winding. Power is connected to each of the three points of the triangle.For more information see the answers to the Related Questions shown below.
