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 slightly, the body returns to its original position (the center of gravity rises). fizika 10 miakishev konspekt uroka po teme statika
The vector sum of all external forces acting on the body must be zero. The point through which the resultant of all
Statics is the branch of mechanics that studies the conditions for the equilibrium of bodies. Equilibrium is a state where a body remains at rest or moves uniformly and rectilinearly relative to a chosen inertial frame of reference. 2. Key Concepts The vector sum of all external forces acting
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
