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