): 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).

(Clockwise moments are usually considered negative, and counter-clockwise moments positive).

The point through which the resultant of all gravitational forces acting on the particles of the body passes, regardless of the body's orientation. For simple geometric shapes made of uniform material, it coincides with the geometric center. fizika 10 miakishev konspekt uroka po teme statika

To ensure a body does not move translationally or rotate, two conditions must be met simultaneously:

If displaced slightly, the body returns to its original position (the center of gravity rises). ): The shortest distance (perpendicular) from the axis

An idealized model of a body where the distance between any two of its points remains constant, regardless of the forces applied.

The vector sum of all external forces acting on the body must be zero. The point through which the resultant of all

An infinite line passing through the force vector. Lever Arm (
