The crank OA of the four-bar linkage is driven at a constant counterclockwise angular velocity w₀ = 10 rad/s. Determine and plot as functions of the crank angle θ the angular velocities of bars AB and BC over the range 0 ≤ θ ≤ 360°. State the maximum absolute value of each angular velocity and the value of θ at which it occurs.
