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 forces balance of force resolution of forces. independence of forces forces balance of force resolution of forces. ANSWER DOWNLOAD EXAMIANS APP
