This calculator is based on Chapter 3.16 and Chapter 7.8 of Shigley's Mechanical Engineering Design. It seems to work as far as I can tell, however, use it at your own risk. That is to say, by using this calculator, you are accepting all related risks associated with it. At the end of the day, you're responsible for any engineering designs you release. Make sure fit them up and test them out. In other words, do your due diligence to ensure best results. Beyond that, the calculator is also subject to the typical theoretical limitations inherent in all calculations. Namely, garbage in, garbage out. Ensure you use correct numbers for best results. Good luck and enjoy. It took a few weeks to put together and make everything look pretty.
