Velocity analysis of four bar mechanism

Velocity analysis of four bar mechanism Let ω2, ω3 and ω4 be the angular velocities of the links 2,3 and 4 respectively. ω2 is the input angular velocity of the link 2. Since the link lengths a, b and c are known and for the given θ2 value, θ3 and θ4 can be determined using position analysis. The angular velocities ω3 and ω4 are given by
