According to Newton'sfirst law, a particle is said to be in equilibrium if there is no net force acting on it. This does not mean that no forces act on the particle, but rather that the resultant of all the forces which do act on the particle is zero. Jan 22, 2008 · Because the object is in equilibrium we know that the Y component of F3 must be equal and opposite of the sum of F1 and F2's Y components, or 74.641 N. Now the X component, F1 has no X component (42 Cos 90 = 0) and F2's X component would be -40 Cos 60 = -20 N. Summing the X components, 0 - 20 = -20 N, now taking the opposite for F3 would be 20 N.
respectively. In this way the given system of forces F1, F2, F3 and F4 is replaced by a system of eight forces applied at points 1, 2, 3 and 4. Since the components BO and OB acting along the action line ob form a pair of equal, opposite and collinear forces, they are in equilibrium and eliminate or neutralize each other and therefore may be removed from the system.

Jan 02, 2010 · Engineers use 'free body diagrams' to visualize the action of forces within a system. This is done by isolating the part of the body that needs to be studied by cutting it, and then introducing forces to keep the isolated body in equilibrium. The forces required to keep the body in equilibrium indicate the nature of forces acting within the body.
If an object is in (translational) equilibrium, then the vector sum of all forces acting on it must be zero. The acceleration of the center of mass of the object must be zero when viewed from an inertial reference frame. ΣF = 0. ΣF = F1 + F2 + F3 + . . . = 0. Second Condition of Equilibrium (Coplanar Equilibrium).
