It is equal to the resultant force in magnitude but opposite in direction.ģ. The force, which brings the set of forces in equilibrium is called an equilibriant. ![]() ![]() Such a set of forces, whose resultant is zero, are known as equilibrium forces. If the resultant of a number of forces, acting on a particle, is zero then the particle will be in equilibrium. If the resultant (R) makes an angle α with the horizontal, thenĢ. In such cases, resultant of the forces is given by The resultant of more than two intersecting forces may be found out by resolving all the forces horizontally and vertically. in beams: area method and, 313 bending moment in, 289 torque in, 289 couplevector,79 definition of, 76 equivalent, 78 line of action of a force changing. It states that if a number of forces, acting simultaneously on a particle, be represented in magnitude and direction by sides of a polygon taken in order, then their resultant is represented in magnitude and direction by the closing side of the polygon taken in opposite order.ġ. It states that if two forces, acting simultaneously on a particle, be represented in magnitude and direction by the two sides of a triangle taken in order, then their resultant may be represented in magnitude and direction by the third side of the triangle taken in opposite order.ģ. It states that if two forces, acting simultaneously on a particle, be represented in magnitude and direction by the two adjacent sides of a parallelogram, then their resultant may be represented in magnitude and direction by the diagonal of a parallelogram which passes through their points of intersection.įor example, let us consider two forces P and Q acting at angle θ at point O as shown in Fig.
