Engineering Mechanics The forces, which meet at one point, but their lines of action do not lie in a plane, are called Intersecting forces Non-coplanar non-concurrent forces Coplanar non-concurrent forces Non-coplanar concurrent forces Intersecting forces Non-coplanar non-concurrent forces Coplanar non-concurrent forces Non-coplanar concurrent forces ANSWER DOWNLOAD EXAMIANS APP
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
