The following is an extended free body diagram of an object. The X represents the xed axis of rotation about which the object can turn. It will not rotate around any other axis. You can assume the object is purely horizontal and that all the forces acting on it are purely vertical. You can also assume that all the forces have the same magnitude. In this case, which of the following statements about this object is true? 0 The object is in equilibrium because the sum of forces is zero. 0 The object is not in equilibrium because the sum of torques is not zero. 0 The object is in equilibrium because the sum of forces is zero and the sum of torques is zero. 0 The object is in equilibrium because the sum of torques is zero. 0 The object is not in equilibrium because the sum of the forces is not zero
