Q-3 For the mechanism shown, below, A0 and D0 are fixed joints (fixed pivots); a) Write the loop closure equations in polar complex form. [15 pts.] b) Write the loop-closure equations by separating real and complex parts. [10 pts.] [Nates: BAD is one link (Link-3). For the angular position of link AB : ?Aa=2??(?1??12). Link D0D is perpendicular to link AD. Therefore, we have: D0=a6e(012+?/2) or D0D=a6e(013+3?/2). Also, in the figure, points G and H are treated as auxiliary points when going either from A0 to C or from A0 to D0.
