(Clockwise moments are usually considered negative, and counter-clockwise moments positive).
An infinite line passing through the force vector. Lever Arm (
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 fizika 10 miakishev konspekt uroka po teme statika
If displaced slightly, the body moves further away from its original position (the center of gravity lowers).
If displaced slightly, the body returns to its original position (the center of gravity rises). ∑Mi=0sum of cap M sub i equals 0
The vector sum of all external forces acting on the body must be zero.
To ensure a body does not move translationally or rotate, two conditions must be met simultaneously: To ensure a body does not move translationally
An idealized model of a body where the distance between any two of its points remains constant, regardless of the forces applied.
