Principle
Coplanar forces (weight, spring balance) act on the moments disc on either side of the pivot. In equilibrium, the moments are determined as a function of the magnitude and direction of the forces and of the reference point.
Benefits
- Understand the relation and the difference between moments and force.
- Smart designed equipment that makes measurements clear and easy.
- The famous quote of Archimedes in its quantitative formulation of todays physics: "Give me the place to stand, and I shall move the earth."
Tasks
- Determination of the moment as a function of the distance between the origin of the coordinates and the point of action of the force.
- Determination of the moment as a function of the angle between the force and the position vector to the point of action of the force.
- Determination of the moment as a function of the force.
