Spring

The Spring is a type of rod. it looks like a generic yellow spring, somewhat similar to poly bridge or Algodoo. It functions like you would expect, compressing to at most half its original length and extending to (5/3)x its original length. The rate at which it contracts/extends is determined by this formula:

$$f(x) = \begin{cases} \surd x, & \text{if }x\text{ is contraction } \\ (1/log_{2x}(10))\times17.5, & \text{if }x\text{ is expansion} \end{cases}$$

It's weight is equal to 85% of a wooden rod's.
