This lab was very interesting , since it the main concept revolves around a lifting mechanism called linkages . We did some activities by exploring the different types of linkages that exist . Some of the linkages that we learned in class are shown below in the diagram. We modeled all of the linkages in cardboard and recorded the measurements , we also learned special terms for each of the links such as coupler, follower, crank and ground links . This Lab basically helped us to understand the different types of linkages and their characteristics such as the arc path that each linkage has. The second part of the lab we also investigated the special types of linkages known as the hoecken and chebyshev linkage (Diagram shown below). Before I did not know what a linkage is but now after doing the lab , I understand what the applications of linkages are and also how each one of them work according to their characteristics.
