What is An equal-arm balance used to measure?

Answer 1

The thing you put weights on is called the pan. The thing that is horizontal and has the pans attached to it is called the arm. The triangle on the arm is the fulcrum. The scale is the lines on the base that sometimes have numbers below each line. The base is the bottom half of the balance. The metal pieces that are on both sides of the arm, they are adjustable, are the metal riders. The pointy piece that is under the fulcrum, it moves when you measure, is the pointer.
