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.
