FINITE ELEMENT ANALYSIS x Figure 10: Joint Stiffness Calculation Kx For the stiffness Ky, the load was applied as a moment. The equation simplifies, not needing to include the additional length to the center of rotation, and is shown in Figure 11. y Figure 11: Joint Stiffness Calculation Ky The calculated stiffness for the five joints is listed in Table 1.
