A uniform beam released from a horizontal position.
A uniform beam released from a horizontal position.
A uniform thin beam is pivoted at one end and held in a horizontal position. The beam is released from rest and allowed to swing downward. Air resistance and friction at the pivot are negligible. Which of the following graphs best represents the magnitude of the angular acceleration \( \alpha \) of the beam as a function of time \( t \) from the moment of release until the beam reaches the vertical position?
