2. The mechanism shown in the figure below is driven by link 2 at ω 2 = 45 rad/s,
CCW. Find the angular velocities of links 3 and 4.
Take O2O4 = 10 cm, O2A = 4 cm, AB = 10 cm, O4B = 12 cm, and θ2 = 1200.
3. Link 2 of the mechanism shown in the figure below is driven at an angular
velocity of 36 rad/s, CW. Find the angular velocity of link 3 and the velocity of
point B.
Take AO2 = 5 cm, O4O2 = 7 cm, AB = O4B = 8 cm, and θ2 = 300.
