Engineering Mechanics Varingon's theorem of moments states that if a number of coplanar forces acting on a particle are in equilibrium, then Their lines of action are at equal distances The algebraic sum of their moments about any point is equal to the moment of their resultant force about the same point The algebraic sum of their moments about any point in their plane is zero Their algebraic sum is zero Their lines of action are at equal distances The algebraic sum of their moments about any point is equal to the moment of their resultant force about the same point The algebraic sum of their moments about any point in their plane is zero Their algebraic sum is zero ANSWER DOWNLOAD EXAMIANS APP
Engineering Mechanics The rate of change of momentum is directly proportional to the impressed force, and takes place in the same direction in which the force acts.
