I am looking for a simple number which is the potential energy that can be stored in rubber. ( Joules per gram or something similar ) I know there are a number of forms of rubber and I keep reading numerous articles on how to calculate the energy content of a rubber band.
Can anyone just tell me the number for typical rubber available commercially ??
I am building a rubber band "vehicle" and I am starting off with a test bed of one band approx 3m long made up of say 50 strands which will run as a model airplane would but driving the rear wheel. I can pretty much work out frictional losses through the drive system and what horsepower I need to get up to certain speeds but before I run the test vehicle on the road I would be interested to compare the theoretical number against that actually achieved.
There must also be a optimum diameter for the band itself expressed as a ratio to the length which I am trying to find out from the modelling world but if anyone has that number I would be grateful to hear it.
Thanks
Simon
