Condisons of eqillybirium motion |
| Answer» A body is said equilibrium if the resultant of all the forces acting on it is zero.Let n number of forces F1,F2,F3,……,Fn are acting on a body such that:F1 +F2+F3+……+Fn =0or ∑ F =0 ……(1)The second condition for equilibrium when the resultant torque acting on it is zero.Mathematically:∑ τ =0. | |
