A Jolly balance, also known as a Jolly balance scale or Jolly balance beam, is a type of balance scale used in educational settings and laboratories to demonstrate the principles of mass and weight measurement. It consists of a horizontal beam that is pivoted at a central fulcrum. Different weights can be placed on either side of the beam, and the balance will tip to one side or the other based on the relative masses of the weights.
