56. REASONINGSince the wire beneath the limb is at rest, it is in equilibrium and the net force acting on it must be zero. Three forces comprise the net force, the 151-N force from the limb, the 447-N tension force from the left section of the wire, and the tension force Tfrom the right section of the wire. We will resolve the forces into components and set the sum of the xcomponents and the sum of the ycomponents separately equal to zero. In so doing we will obtain two equations containing the unknown quantities, which are the horizontal and vertical components of the tension force T. These two equations will be solved simultaneously to give values for the two unknowns. Knowing the components of the tension force, we can determine its magnitude and direction. SOLUTIONLet Txand Tybe the horizontal and vertical components of the tension
