Figure 9.8. Constraint violation and phase difference between input driver and driven
body. This is done for a moderate joint angle of 5 . Both constraint definitions introduce
only a small phase difference.

Figure 9.9. Constraint violation and phase difference between input driver and driven
body. Here, the angle is more pronounced at 20 . The result is that the CV joint does
still follow the driver with a small phase difference. The Hooke joint deviates significantly
from the input driver.
