The above diagram shows the forces mentioned in prior
sections as they are applied to different areas of the bow
at full draw. The bow is in static equilibrium because it is
not accelerating, ie held in place by the archer and
internal forces. When the archer no longer applies the
vertical and horizontal forces at joint 2 the bow will leave
static equilibrium. More on this in The Bow: Post Release.
In the diagram for this discussion I am lumping the mass of the arrow into the bow for a more complete breakdown the components of its weight should be found at each joint 4 and 2. Below is a diagram showing the approximate force due to gravity for the entire system of the bow, separate from the above for clarity.
