View answer & explanation

Correct answer

Answer: (a)A.

First

Why this answer is correct

The correct answer is First.

Key Points

  • A common balance (or a beam balance) is an example of a first-class lever.
  • In a first-class lever, the fulcrum (pivot point) is situated between the effort and the load. In simple terms, it's the spot where the lever rotates or pivots.
  • For a common balance, this is clearly seen as the following:
  • The effort is applied at one end (you place an object on one balance pan), the load is at the other end (you place counterweights on the other balance pan), and the fulcrum is in the middle (the point around which the balance beam rotates).
  • When a common balance is balanced, it means that the effort times its distance from the fulcrum equals the load times its distance from the fulcrum.
  • First class levers are the most familiar in our daily lives as they include tools like scissors, pliers, seesaws, and crowbars.

Additional Information

  • A second-class lever is one where the load is between the effort and the fulcrum, like in a wheelbarrow or a nutcracker or a door opened by a handle.
  • A third-class lever is when the effort is between the load and the fulcrum, like in a pair of tweezers or a human arm (with the elbow as the fulcrum, the biceps muscle providing the effort, and the load in the hand).
