WebThe three moving parts of this mechanism (the base is not moving) are: link P 1 -A, link P 2 -B, and body BAC. For each of these three parts an instant center of rotation may be determined. Considering first link P 1 -A: all points on this link, including point A, rotate around point P 1. WebAPPLICATION OF THE FOUR-BAR LINKAGE TO PROSTHESES Let us now consider the applications of a four-bar linkage as a knee mechanism . The shank of the prosthesis is considered to be the frame linkage, and the socket and knee block constitute the coupler (Fig . 3a). The center of rotation of the coupler relative to the frame is the instant center I. http://www.oandplibrary.org/poi/1994_03_159.asp rajasthan ki gk questions
