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