Fizika 10 Miakishev Konspekt Uroka Po Teme Statika ◆

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

If displaced, the body remains in its new position (the height of the center of gravity does not change). fizika 10 miakishev konspekt uroka po teme statika

If displaced slightly, the body returns to its original position (the center of gravity rises). An idealized model of a body where the

): 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). ): The shortest distance (perpendicular) from the axis

The algebraic sum of the moments of all external forces about any axis of rotation must be zero. ∑Mi=0sum of cap M sub i equals 0

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

If displaced slightly, the body moves further away from its original position (the center of gravity lowers).
