developable surface meaning in Hindi

Examples

1. The cone and the plane are all developable surfaces.
2. Formally, in mathematics, a developable surface is a surface with zero Gaussian curvature.
3. In particular, the twisted paper model is a developable surface, having zero Gaussian curvature.
4. Developable surfaces have several practical applications.
5. While the first step inevitably distorts some properties of the globe, the developable surface can then be unfolded without further distortion.
6. The three developable surfaces ( plane, cylinder, cone ) provide useful models for understanding, describing, and developing map projections.
7. Because of this, many developable surfaces can be end-point of a line fixed whilst moving the other end-point in a circle.
8. An important class of such surfaces are the developable surfaces : surfaces that can be flattened to a plane without stretching; examples include the cone.
9. A surface that can be unfolded or unrolled into a plane or sheet without stretching, tearing or shrinking is called a " developable surface ".
10. If at least one of the principal curvatures is zero at every point, then the Gaussian curvature will be 0 and the surface is a developable surface.
