Rubber Sheet Geometry Exampl

A sheet of rubber especially one from which shapes can be cut or which is used to protect against water dirt etc.

A circle can be stretched into a square with a rubber band but you can t stretch a figure eight into a circle without tearing. Topology branch of mathematics sometimes referred to as rubber sheet geometry in which two objects are considered equivalent if they can be continuously deformed into one another through such motions in space as bending twisting stretching and shrinking while disallowing tearing apart or gluing together parts. Concept of topology rubber sheet geometry topology does not distinguish between a circle and a square but it does between a circle and a figure eight. Thus if you need a rubber or o ring durometer that feels like a running shoe sole review our rubber hardness chart below then pick shore 70a.

For example a square can be deformed into a circle without breaking it but a figure 8 cannot. Generally most rubber materials fall under the rubber durometer scale of shore a. It is sometimes called rubber sheet geometry because the objects can be stretched and contracted like rubber but cannot be broken. The placer is a geometry manager for tk.

Hence a square is topologically equivalent to a circle but different from a figure 8. It provides simple fixed placement of windows where you specify the exact size and location of one window called the slave within another window called the master the placer also provides rubber sheet placement where you specify the size and location of the slave in terms of the dimensions of the master so that the slave changes size.
