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 balance of force resolution of forces. forces independence of forces balance of force resolution of forces. forces independence of forces ANSWER DOWNLOAD EXAMIANS APP
Strength of Materials A semi-circular disc rests on a horizontal surface with its top flat surface horizontal and circular portion touching down. The coefficient of friction between semi-cricular disc and horizontal surface is i. This disc is to be pulled by a horizontal force applied at one edge and it always remains horizontal. When the disc is about to start moving, its top horizontal force will slant down towards direction of pull unpredictable slant up towards direction of pull remain horizontal slant down towards direction of pull unpredictable slant up towards direction of pull remain horizontal ANSWER DOWNLOAD EXAMIANS APP
