Force is a quantity on which many other quantities such as torque, thrust and pressure are based.
Accurate force measurements are required in many applications. These include the determination of the strength of materials, quality control during production, weighing, and consumer safety. For example, force measurement systems are used to determine when a missile has developed sufficient thrust to be released for takeoff and in auto safety tests. In the aircraft industry, force measurements are required to test the structural integrity of aircraft components and structures. In the picture on the left, force sensors are used to test the structural integrity of the wings, fuselage, and fasteners used in aircraft production.
