23 12 2 2 2 b l k + = (5) where l & b are the length & breath of the bar respectively. Experimental Procedure: 1. Determine the center of mass (CM) by balancing the bar on a knife-edge. Measurement of d is made from this point to the point of suspension for each hole. 2. Suspend the bar by means of knife-edge. 3. Focus the telescope on to the marker marked on the pendulum. There should not be any parallax between the image of the marker and the cross wire in the eyepiece of the telescope. 4. Measure the time for 10 to 20 oscillations for different d (only on one side of CM). Repeat each observation several times. Plot T Vs d . Calculate
