Moments

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.

Tasks

1. Determination of the moment as a function of the distance between the origin of the coordinates and the point of action of the force.
2. 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.
3. Determination of the moment as a function of the force.
