Example 9-10 A Uniform Rod, Pivoted at One End A uniform thin rod of length  and mass  is pivoted at one end. It is held horizontal and  released. Effects due to friction and air resistance are negligible. Find ( a ) the angular acceleration  of the rod immediately following its release, and ( b ) the magnitude of the force  F A  exerted on the  rod by the pivot at this instant. PICTURE  The angular acceleration is found from Newton’s second law for rotation ( Equation       9-     19 ). The force  F A  is found from Newton’s second law for a system ( Equation       5-23     ). The tangential  acceleration of the center of mass is related to the angular acceleration ( Equation       9-6     ), and the  centripetal acceleration of the center of mass is related to the angular speed ( Equation       9-7     ).
