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 Maximum, if it acts at the center of gravity of the body Minimum, if it acts at the center of gravity of the body Same at every point on its line of action Different at different points on its line of action Maximum, if it acts at the center of gravity of the body Minimum, if it acts at the center of gravity of the body Same at every point on its line of action ANSWER DOWNLOAD EXAMIANS APP
Engineering Mechanics The three forces of 100 N, 200 N and 300 N have their lines of action parallel to each other but act in the opposite directions. These forces are known as Like parallel forces Unlike parallel forces Coplanar non-concurrent forces Coplanar concurrent forces Like parallel forces Unlike parallel forces Coplanar non-concurrent forces Coplanar concurrent forces ANSWER DOWNLOAD EXAMIANS APP
