Strength of Materials The algebraic sum of the resolved parts of a number of forces in a given direction is equal to the resolved part of their resultant in the same direction. This is as per the principle of independence of forces resolution of forces. forces balance of force independence of forces resolution of forces. forces balance of force ANSWER DOWNLOAD EXAMIANS APP
Strength of Materials According to principle of moments positive and negative couples can be balanced if a system of coplanar forces is in equilibrium, then the algebraic sum of their moments about any point in their plane is zero if a system of coplanar forces is in equilibrium, then their algebraic sum is zero the algebraic sum of the moments of any two forces about any point is equal to moment of theiwesultant about the same point positive and negative couples can be balanced if a system of coplanar forces is in equilibrium, then the algebraic sum of their moments about any point in their plane is zero if a system of coplanar forces is in equilibrium, then their algebraic sum is zero the algebraic sum of the moments of any two forces about any point is equal to moment of theiwesultant about the same point ANSWER DOWNLOAD EXAMIANS APP
