mechanism to the maximum force position. Either a force or a displacement could have been applied with the
actuator. The CNVTOL commands are added to eliminate minimum reference value warnings in the output.
The maximum force exerted by the mechanism upon the spring occurs when the lower links are colinear and
parallel to the input lever. The revolute joint connecting the two lower links locks up when a stop engages, after
a rotation of 2 α degrees, to simulate the self-locking behavior of the mechanism. Results Comparison
