1. The problem statement, all variables and given/known data 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 2. Relevant equations - 3. The attempt at a solution I'm not looking for someone to do it for me. Just trying to figure out exactly what he means by using an angle measurement for weight. Any hints, examples, and pushes in the right direction would be appreciated.
