Rubber sheet geometry noun a humorous name for topology.
The placer is a geometry manager for tk.
Generally most rubber materials fall under the rubber durometer scale of shore a.
For example a square can be deformed into a circle without breaking it but a figure 8 cannot.
It is sometimes called rubber sheet geometry because the objects can be stretched and contracted like rubber but cannot be broken.
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.
Hence a square is topologically equivalent to a circle but different from a figure 8.
The main topics of interest in topology are the properties that remain.
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.
A rubber durometer of shore 70a is the most commonly chosen material hardness for all applications.
