The mechanism used in a marine engine consists of a single crank AB and two connecting rods BC and BD as shown in (Figure 1). Assume r = 0.2 m Part A Determine the magnitude of the velocity of the piston at D the instant the crank is in the position shown and has an angular velocity of w 4 rad/s. Express your answer with the appropriate units. НА VD = Value Units Submit Request Answer Part B Determine the direction of the velocity of the piston at D the instant the crank is in the position shown and has an angular velocity of w = 4 rad/s.
