An idealized model of a body where the distance between any two of its points remains constant, regardless of the forces applied.
To ensure a body does not move translationally or rotate, two conditions must be met simultaneously: fizika 10 miakishev konspekt uroka po teme statika

(Clockwise moments are usually considered negative, and counter-clockwise moments positive). ): The shortest distance (perpendicular) from the axis
If displaced slightly, the body moves further away from its original position (the center of gravity lowers).
): The shortest distance (perpendicular) from the axis of rotation to the line of action of the force. The product of the magnitude of the force ( ) and its lever arm ( M=F⋅dcap M equals cap F center dot d Units: Newton-meters (N·m).
If displaced slightly, the body returns to its original position (the center of gravity rises).
