12-6) Your doctor's scale uses a slidable weight on an arm to balance your weight. These weights are obviously much lighter than you are. How does this work?
Please help, thanks!

These scales work because of torque. It is like Archimedes said, "Give me a place to stand and with a lever I will move the whole world."

The further the weight is from a fulcrum (^) the more force it applies.

Have you ever heard of a fulcrum ? Go into your geometry or first year physics books, find the chapters on fulcrums and see if they replicate the doctor's scale.Will that help solve the problem?
