ABCD is a four bar chain with link AD fixed. The lengths of the
links are AB = 62.5 mm;
BC = 175 mm; CD = 112.5 mm; and AD = 200 mm. The crank AB rotates
at 48 rad/s
clockwise. Draw the velocity and acceleration diagram when angle
BAD = 60° and B and
C lie on the same side of AD. Find the angular velocity and angular
acceleration of links
BC and CD.
