Engine mechanicals How do torques cancel each other out?

Moments cancel each other out when the force counteracts a force of equal magnitude at equal distances from the pivot. Example 1: Example 1: q

Three weights are located on the balance. Weight A is on the left-hand side and weights B1 and B2 are on the right-hand side. As weights B1 + B2 are equally as heavy as weight A, the force and counterforce cancel each other out, i.e. a force equilibrium exists.

or:

Moments cancel each other out when a counterforce of half the magnitude counteracts the force at twice the distance from the pivot. Example 2: Example 2: q

Two weights are located on the balance. Weight A is on the left-hand side and weight B is on the right-hand side. Weight B is located twice the distance away from the pivot. As a result, the torques on both pages are equalised and a force equilibrium exists.
