FIGURE P4-3 Problems 4-11 to 4-12 Terminology for inversion #3 of the fourbar crank-slider linkage *14-10 Repeat Problem 4-9 except solve by the vector loop method. *4-11 The link lengths and the value of 02 and y for some inverted fourbar crank-slider link- ages are defined in Table P4-3. The linkage configuration and terminology are shown in Figure P4-3. For the rows assigned, draw the linkage to scale and graphically find both open and crossed solutions for angles 03 and 04 and vector Rg. *+4-12 Repeat Problem 4-11 except solve by the vector loop method.
hi I was wondering if I could get help with 4-12 for c and e ?

The major distinction between freely moving entities and moving links in a mechanism is that the latter have constrained motion due to the joints that connect them. We'll call the closed polygons formed by the links joined by joints a loop. The mathematical expression of these loops is used to analyse the motion of machinery.
In kinematic analysis, we'll assume that all of each link's essential dimensions are known, and that link length dimensions (i.e., the distance between joints or angles) can be calculated from the known dimensions using the link's geometry.
