In the study of mechanisms, a four-bar linkage, also called a four-bar, is the simplest closed-chain movable linkage. It consists of four bodies, called bars or links, connected in a loop by four joints.

The West Branch is the more pure of the two, owing mostly to the fact that a large portion of it runs through wilderness, making for very fine smallmouth ...
Population in the Rockville city limits (of which only a portion is in the Watts Branch watershed) more than doubled between 1960 and 2010, from approximately 26,000 to 61,000.
