DEVELOPMENT OF SURFACES
Prepare By M.FAHADCell no +923334040537
INTRODUCTION
When Surfaces of a solid are laid out on a plane the figure obtained is called DEVELOPMENT
METHODS OF DEVELOPMENT
There are four main types of developments Parallel- line development Radial –line developmentTriangulation development Approximate Method
PARALLEL-LINE DEVELOPMENT
It is employed in case of prisms and cylinders in which stretch –out-line principle Is used.
RADIAL-LINE-DEVELOPMENT
It is used for pyramids and cones in which the true length of the slant edge or the generator is used as radial.
TRIANGULATION DEVELOPMENT
This is used to develop transition pieces. This is simply a method of dividing a surface into a number of triangles and transferring them into the development.
APPROXIMATE METHOD
It is used to develop object of double curved or warped surface as Sphere, Parabolic, Ellipsoid, Hyperboloid and the Helicoids.
WHAT IS CUBE
In geometry a cube is a three-dimensional solid object bounded by six square faces, facets or sides, with three meeting at each vertex.
CUBE
The development of the surface of the cube consist of six equal squares the length of the side of the squares being equal to the length of the edge of the cube
