Home courses courses under refinement (version 2. 0) ug courses - agricultural engineering (version 2. 0) engineering mechanics . Definition of force" can be given in several ways. The cause of change in the state of motion of a particle or body". It is of course, the product (multiplication) of mass of the particle and its acceleration. Force is the manifestation of action of one particle on the other. A force has following basic characteristics: magnitude, direction, point of application, line of action. Force is represented as a vector . i. e an arrow with its magnitude. e. g. for the force shown in fig. 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. Smaller magnitudes of forces are measured in newton (n) and larger in kilonewton (kn). When a mechanics problem or system has more than one force acting, it is known as a.
