![]() When the line of action of all the forces do not lie in one plane, is called Non-coplanar force system When the lines of action of a set of forces lie in a single plane is called coplanar force system. When the lines of action of all the forces of a system act along the same line, this force system is called collinear force system. When a mechanics problem or system has more than one force acting, it is known as a ‘force system’ or ‘system of force’. Smaller magnitudes of forces are measured in newton (N) and larger in kilonewton (KN). ![]() 2.1, magnitude of force is 4KN, direction is 40° with the horizontal in fourth quadrant, point of application is C and line of action is AB. A Force has following basic characteristicsįorce is represented as a vector.
