Determine the resultant force that both of these liquids exert on the side abc of the tank2/24/2024 ![]() Note that the vector for a resultant force has a double arrowhead to distinguish it from the other forces acting in the system.ĭrawn to a scale of 1 cm =5 N, the vector representing F1 will be 4 cm long and the vector representing F2 will be 5 cm long. This is the force FR shown in the Fig (b). Since both the forces F1 and F2 have a common line of action and act in the same direction, their vector lengths can simply be added together to obtain the magnitude of the vector of the single force that can replace them. ![]() For example, the forces F1 and F2 acting in the same direction on the point P along the same line of action can be replaced by a single force having the same effect as shown in Fig. We call a force that can replace two or more other forces and produce the same effect a resultant force. ![]() Resultant force – It has already been stated that forces cannot be seen so they cannot be drawn however, the effect of forces and systems of forces can be represented by vectors.
