type: OTHER
Source sentences:
text: With four pin-connected links, for example, the links all move in parallel planes, and regardless of which link is fixed, the other links have constrained motion; i.e., they move in a fixed and determinate way relative to the fixed link.
text: Generally, the joints are configured so the links move in parallel planes, and the assembly is called a planar four-bar linkage.
