Answer:
, (plug in the value of BD to get the answer, you did not provide it in your question)
Explanation:
Absolute acceleration of point B, = 4 m/s²
Absolute acceleration for point D, = 3 m/s²
Acceleration of point B relative to D in the normal direction BD, = 0 (the cable moves with constant velocity)
Acceleration of point B relative to D in the tangential direction to BD, = ?
The equation for the relative acceleration for the motion between B and D:
To determine the angular acceleration of the beam
Note: You did not provide the value for the distance between B and D, this value is needed to calculate the angular acceleration. Plug in the value for BD and get your answer
