Homework Help: Tube structure of steel rollercoasters

  1. Jan 22, 2005 #1
    I was wondering if anybody knew the type of steel that is used for the tube structure of steel rollercoasters and also its youngs modulus. I also need to know the youngs modulus for the polyurethane wheels they run on. I need this informattion for a new science project and have looked everywhere with no joy. please help

    Most steels that would be used are relatively close together in terms of Young's modulus. If you use 30x10^6 lbf/in^2 you will be fine. If you want other properties of the material then it would be advisable to research the exact alloy. Sorry I can't help you on the polyurethane material.
