<div class="wp-block-create-block-problemblock">A uniform rod of mass M and length L is attached to a pivot of neglible friction as shown below.  The pivot is located at a distance ##\frac{L}{3}## from the left end of the rod.  Express all answers in terms of the given quantities and fundamental constants.<br /><img src=/old/images/oscillation.gif alt="physics pivot oscillation problem ><br />A. Calculate the rotational inertia of the rod about the pivot.<br />B. The rod is then released from rest from teh horizontal positon shown above.  Calculate the linear speed of the bottom end of the rod when the rod passes through teh vertical.<br />C. The rod is brought to rest in teh vertical posoition shown below and hangs freely.  It is then displace slightly from this position.  Calculate the period of teh osciallation as it swings.<br /><img " src="/old/images/oscillation2.gif"  alt="physics pivot oscillation example "></div>
