WebFOUR-BAR MECHANISM. A four-link mechanism with four revolute joints is commonly called a four-bar mechanism. Application of four-bar mechanisms to machinery is numerous. Some typical applications will involve: ... Grashof's theorem (or Grashof’s rule) gives the criteria for these various conditions as follows: WebF. Grashof classified four bar mechanisms into three types (double-cranks, rocker cranks, and double-rockers) and gave a set of rules for identifying the different types.

One link of the chain is usually fixed, and is called the ground link, fixed link, or the frame. The two links connected to the frame are called the grounded links and are generally the input and output links of the system, sometimes called the input link and output link. The last link is the floating link, which is also called … easter bird nests chow mein noodles
