Grashof’s Law CivilMint.Com

Planar quadrilateral linkage, RRRR or 4R linkages have four rotating joints. 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 … WebExpert Answer. Transcribed image text: Problem 3 For the values given in each row of the Table 1, draw all possible solutions.
