Mr.Brown is requesting a cheaper version of a Dynamics Track for his physics class. It must have adjustable feet for leveling, be rigid, and have graduations(length measurements).

- Is the 1.2 or 2.2 meter track requested?
- Are there any other elements of the cross section that need to be replicated other than being able to hold a marble (such as the width or the grooves on the side), that would be needed to use any other equipment?
