Locate all the instantaneous centres for the crossed four bar mechanism as shown in Fig. 6.28. The dimensions of various links are : CD = 65 mm; CA = 60 mm ; DB = 80 mm ; and AB = 55 mm. Find the angular velocities of the links AB and DB, if the crank CA rotates at 100 r.p.m. in the anticlockwise direction.
