I am wanting to create my own Dynamometer for my physics class. (Im a student by the way.) I want to leave something behind. This teacher has really helped me get through this class and make it very enjoyable at the same time. And for the class we are suppose to make a project or test a theory. Before the end of the semester we will be doing a 'tug of war' thing using phone books as a way to have a bit of fun before finals. I would really like to be able to measure that force with a dynamometer. She has told the class they were going to use one before but everyone who has promised to let her previous classes use them has backed out at the last minute. Well to get to my point, does anyone have any ideas how one could go about making their own dynamometer?
