Question:
The uniform slender bar of mass m pivots freely about a horizontal axis through O. If the bar is released from rest in the horizontal position shown where the spring is unstretched, it is observed to rotate a maximum of 30? clockwise. The spring constant ? = 200 N/m and the distance b = 200 mm. Determine
(a) The mass m of the bar and
(d) The angular velocity w of the bar when the angular displacement is 15? clockwise from the release position.
