State two conditions necessarily for a body to acted upon by a coplanar forces

Physics

ScanSolve AI Answer

Here are two conditions necessary for a body to be in equilibrium when acted upon by coplanar forces:

  1. Translational Equilibrium: The vector sum of all forces acting on the body must be zero. This means the sum of the components of the forces in any two mutually perpendicular directions (e.g., horizontal and vertical) must each be zero.
  2. Rotational Equilibrium: The algebraic sum of the moments (torques) of all forces about any point in the plane must be zero. This ensures the body does not rotate.
