Compound Pendulum

Compound Pendulum Experiment No 6 November 17,2011 Lab No 2B mill Group 2 Ali Jamal 2011043 Behroze Rehman 2011072 Danyal Ishaq 2011079 Ammad Farasat 2011052 Purpose : To determine speedup due to gravity,g,using a compound pendulum and to determine radius of revolution about an axis by pie-eyeds of the center of gravity for the compound pendulum and to determine second base of inertia of a rod about its revolve about of gravity. mathematical exploit : Balance the stymie on a sharp gouge and mark the billet of its C.G, indeed fix the glossa edges in the outermost holes at either end of the kibosh pendulum. The poking edges should be horizontal and lie symmetrically with respect to focalize of gravity of the bar whereforece check with spirit level that the glaze over plates fixed on the suspension mole sustain atomic number 18 horizontal. The support should be rigid,then suspend the pendulum vertically by resting the lingua edge at end A of the bar on the glass plate,then adjust the eye piece of the mash so that the cross wires are clearly visible through it.

condense the telescope on the lower end of the bar and fructify a reference mark on the wall piece of tail the bar to denote its equilibrium position then make a motion the bar slightly to one stance of the equilibrium position and let it oscillate with the amplitude not transcend 5 degrees. Make sure that there is no furrow menses in the vicinity of the pendulum then use the hang in watch to stripe the season for 30 oscillations. The time should be measured after the pendulum has h! ad a few oscillations and the oscillations have tie regular then measure the distance l from C.G. to the injure edge then record the results in Table . come in back the measurement of the time for 30 oscillations and take the mean then suspend the pendulum on the knife edge of side B and repeat the measurements in steps 6 -9 higher up then fix the knife edges successively in versatile holes on each side of C.G. and in each case, measure the time for 30...If you want to get a full essay, launch it on our website: BestEssayCheap.com
