Engineering Mechanics Varingon's theorem of moments states that if a number of coplanar forces acting on a particle are in equilibrium, then Their algebraic sum is zero The algebraic sum of their moments about any point in their plane is zero The algebraic sum of their moments about any point is equal to the moment of their resultant force about the same point Their lines of action are at equal distances Their algebraic sum is zero The algebraic sum of their moments about any point in their plane is zero The algebraic sum of their moments about any point is equal to the moment of their resultant force about the same point Their lines of action are at equal distances ANSWER DOWNLOAD EXAMIANS APP
Engineering Mechanics The principle of transmissibility of forces states that, when a force acts upon a body, its effect is Same at every point on its line of action Maximum, if it acts at the center of gravity of the body Minimum, if it acts at the center of gravity of the body Different at different points on its line of action Same at every point on its line of action Maximum, if it acts at the center of gravity of the body Minimum, if it acts at the center of gravity of the body Different at different points on its line of action ANSWER DOWNLOAD EXAMIANS APP
