Q-3 For the mechanism shown, below, Ao and Do are fixed joints (fixed pivots); a) Write the loop closure equations in polar complex form. b) Write the loop-closure equations by separating

real and complex parts. [Notes: BAD is one link (Link-3). For the angular position of link AB: 8A = 2n- (a-01). Link DoD is perpendicular to link AD. Therefore, we have: DDo= as e013/2) or DoD = 36.e(013-3/2) Also, in the figure, points G and H are treated as auxiliary points when going either from Ao to C or from A to Do.] bi H C1 00 $36 192 23 96-3/2x+63 Or 3 $15 86 13 30 B 14 G [15 pts.] [10 pts.] X' X
