Bar OA rotates about the fixed pivot O with constant angular velocity = 0.8 rad/s. Pin

Bar OA rotates about the fixed pivot O with constant angular velocity β˙ = 0.8 rad/s. Pin A is fixed to bar OA and is engaged in the slot of member BD, which rotates about a fixed axis through point B. Determine and plot over the range 0 ≤ β ≤ 360° the angular velocity and angular acceleration of BD and the velocity and acceleration of pin A relative to member BD. State the magnitude and direction of the acceleration of pin A relative to member BD for β = 180°.
