Engineering Mechanics The principle of transmissibility of forces states that, when a force acts upon a body, its effect is Different at different points on its line of action Minimum, if it acts at the center of gravity of the body Same at every point on its line of action Maximum, if it acts at the center of gravity of the body Different at different points on its line of action Minimum, if it acts at the center of gravity of the body Same at every point on its line of action Maximum, if it acts at the center of gravity of the body ANSWER DOWNLOAD EXAMIANS APP
