Question

3. Is the weight made of metal ? How is the balance held ? ​

Answer 1

In a slightly different kind of balance called a steelyard, you hang a pan from one end of a metal arm and move a weight along the other end, much like a see-saw, until you find a balance point. ... You put the letters on the pan, move the sliding weight until the arm is horizontal, and then read the weight off the scale.
