Strength of Materials According to principle of transmissibility of forces, the effect of a force upon a body is Maximum when it acts at the center of gravity of a body Different at different points in its line of action The same at every point in its line of action Minimum when it acts at the C.G. of the body Maximum when it acts at the center of gravity of a body Different at different points in its line of action The same at every point in its line of action Minimum when it acts at the C.G. of the body 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 remain horizontal 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 ANSWER DOWNLOAD EXAMIANS APP
