Re: Elastic Potential Energy Stored in Surgical Tubing: What are the legal limits?

Our question is: Is there anything prohibiting using surgical tubing, stretched and secured at the arm's base, as the means of extending the arm in the last 20 seconds. (we will have a latch mechanism in place to be sure that it won't release until our driver hits the button.) Thank you.
You are specifically allowed to do this as per R35

D. closed-loop COTS pneumatic (gas) shocks, and E. air-filled (pneumatic) wheels
What you need to be concerned with is R9

Inspectors will look very closely at your mechanism to ensure that it is safe at all times. This includes when it is being transported on/off the field as well as in the pits, etc.
