    Properties Rubber
AI Thread Summary
Resilience in rubber is crucial as it allows materials to return to their original shape after deformation, which is essential for performance and safety. Tires, although not entirely rubber anymore, benefit from this property by improving stopping ability and traction, preventing slips during turns. Resilient materials are also important in children's playgrounds to ensure safety by absorbing impacts and reducing injury risks. The discussion highlights the role of vulcanized rubber, which enhances durability and performance but also raises questions about potential risks and benefits. Understanding the physics behind these materials is vital for their effective application in various products.

Do you know why it's important for rubber to be resilient?
and does anybody have an example of an object that is made out of rubber which must be resilient?
and does anybody know why it's important why tires and children's play grounds are made from resilient materials?
Many thanks,

Resilient means that they retain their original shape after being deformed.

For a tire (which are no longer made from rubber!) you want a deformation where "the rubber meets the road" ... this improves your stopping ability ... and keeps the vehicle from slipping on turns, etc. But you also want it to "return to round" or you will have a bumpy ride.
 
Vulcanised Rubber

What implications of physics does vulcanised rubber have?
Basically, what are the risks and benefits of vulcanised rubber?
Many thanks,
