To ensure a body does not move translationally or rotate, two conditions must be met simultaneously:
(Clockwise moments are usually considered negative, and counter-clockwise moments positive). fizika 10 miakishev konspekt uroka po teme statika
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 To ensure a body does not move translationally
An infinite line passing through the force vector. Lever Arm ( Lever Arm ( The point through which the
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.
If displaced, the body remains in its new position (the height of the center of gravity does not change).
An idealized model of a body where the distance between any two of its points remains constant, regardless of the forces applied.
