Did you know?
WebA four-bar linkage, also called a four-bar, is the simplest movable closed-chain linkage. It consists of four bodies, called bars or links, connected in a loop by four joints. Generally, the joints are configured so the links move in parallel planes, and the assembly is called a planar four-bar linkage. WebA Simple Four Bar Linakge. A four-bar linkage or simply a 4-bar or four-bar is the simplest movable linkage. It consists of four rigid bodies (called bars or...

After that, the crank was set to 0 in circular scale, and got the rocker scale reading. reading. (angle of the linear scale is same as the rocker scale reading). the linear scale. Finally, the length of the crank, rocker, follower, and frame was measured.
With four-bar mechanisms there are two strokes, the forward and return, which when added together create a cycle. Each stroke may be identical or have different average speeds. The time ratio numerically defines how fast the forward stroke is compared to the quicker return stroke.
