Solution :

OA = 300 mm

AB= 600 mm

AC=BD= 1.2 m

ω=200 rpm=2094 rad/s

1) Relative Velocity Method

enter image description here

By velocity relative Method

The velocity of slider D = 2.04 m/s

2) Instantaneous Centre Method

enter image description here

The velocity of slider D is same as that of angular velocity of link OA

VD=ω or VD=ω(I12I25)

 =2094 mm/s

 =2.094 m/s
