Consider the 2-position design problem depicted below. The mechanism is GRCR. The link lengths and the positions of anchor points O1 and O2 are provided. a. Do any toggle positions exist between configurations CD and C’D’ that would prevent the mechanism from completing the motion? If so, at what angle(s) of θ do they occur? b. Find new values for the coordinates (X,Y) of O2 that would enable the mechanism to be driven by a driver dyad attached to link O1C, e.g., point B. c. What are the coordinates (X,Y) of O2 closest to the origin for which the mechanism can still be driven by a driver dyad attached to link O1C, e.g., point B, as in part b?

Question
Consider the 2-position design problem depicted below. The
lengths and the positions of anchor points O1 and O2 are provided.
a. Do any toggle positions exist between configurations CD and C’D’ that would prevent the
mechanism from completing the motion? If so, at what angle(s) of θ do they occur?
b. Find new values for the coordinates (X,Y) of O2 that would enable the mechanism to be
driven by a driver dyad attached to link O1C, e.g., point B.
c. What are the coordinates (X,Y) of O2 closest to the origin for which the mechanism can
still be driven by a driver dyad attached to link O1C, e.g., point B, as in part b?
