The 6.0-lb bar is pinned at its center O and connected to a
torsional spring. The spring has a stiffness k = 5.6 lb?ft/rad , so
that the torque developed is M=(5.6?)lb?ft, where ? is in
radians.
If the bar is released from rest when it is vertical at
?=90?, determine its angular velocity at the instant
?=45?.
