Abstract: This invention relates to a force and moment balance (1) including a support (9) therefor and more specifically, but not exclusively, to a force and moment balance (1) and a support (9) therefor for a wind tunnel. Force and moment balances are known in the art and are typically used in wind tunnels to measure the force and moment loads on a model in the wind tunnel. A problem with current balances is that there is inherent vertical movement associated with horizontal force. According to the invention, the balance (1) has a fixed end (3) and a movable end (6) with a number of supports (9) between the fixed end (3) and the movable end (6). Each support (9) includes compensation means to compensate for resultant movements caused by lateral movement of the movable end (6) relative to the fixed end (3).
