Answer is:
the algebraic sum of their moments about any point is equal to the moment of their resultant force about the same point.
Explanation:
Varingon's theorem of moments states that if a number of coplanar forces acting on a particle are in equilibrium, then the algebraic sum of their moments about any point is equal to the moment of their resultant force about the same point.
Answer is:
the algebraic sum of their moments about any point in their plane is zero
Explanation:
According to the law of moments, if a number of coplanar forces acting on a particle are in equilibrium, then the algebraic sum of their moments about any point in their plane is zero.
Answer is:
all of the above
Explanation:
For any system of coplanar forces, the condition of equilibrium is that the
algebraic sum of the horizontal components of all the forces should be zero
algebraic sum of the vertical components of all the forces should be zero
algebraic sum of moments of all the forces about any point should be zero
Answer is:
like parallel forces
Explanation:
