Explain the forces involved when 2 people of different weights balance each other out on a see saw?

When two people of different weights balance each other on a see-saw, the force of gravity acting on each person creates a torque or moment that causes the see-saw to rotate about its pivot point. The see-saw remains in equilibrium when the torques from the two individuals are equal, even though their weights are different. The torque is calculated by multiplying the weight of the person by the distance from their center of mass to the pivot point.
