nckalx I know what you mean. I figured out a viable solution that isn't a see saw. But just uses our generic sum of moments =0 and I don't know if that will be okay since he seemed to push the angular measurement. I may send him an email...
Not sure if this is what you were trying to hint at. I think it at least partially is. I will wedge one end of the meter stick into a wall and make that the fulcrum. The object of unknown weight will be placed at a point on this stick. The other end will be held in the air with the wire going...
Correct me if I interpret what you say wrong, but it seems like you are encouraging the use of moments and setting them equal to each other adjusting the pivot point. In which case that seems like it goes against the requirement of not simply balancing them on a see-saw. Or am I completely off...
He said there are many ways we can go about this. He is not strict on any sort of specific solution. As long as we solve the problem in the given parameters. So we don't HAVE to use everything given. I've done plenty of moment summing before in this class. Just his statement about using angle...
Homework Statement
I have to design a scale to weigh something under 1kg and all am given is a yard stick, 10 ft of fishing line, a 500g known standard mass, and a protractor.
Use an angle measurement for weight. Don't just balance weights on a see-saw
