The link lengths, gear ratio (2), phase angle (Ø), and the value of 0₂ for some geared five bar linkages are defined in Table 2. The linkage configuration and terminology are shown in Figure 2. For the rows assigned, find all possible solutions for angles 3 and 4 by the vector loop method. Show your work in details: vector loop, vector equations, solution procedure.
