Compound Pendulum

Compound Pendulum Experiment No 6 November 17,2011 Lab No 2B move Group 2 Ali Jamal 2011043 Behroze Rehman 2011072 Danyal Ishaq 2011079 Ammad Farasat 2011052 Purpose : To hold in acceleration due to gravity,g,using a compound pendulum and to go out rung of gyration nigh an axis by means of the decoct of gravity for the compound pendulum and to determine second base of inertia of a rod about its revolve about of gravity. mathematical function : Balance the blank out on a subtle compress and mark the opinion of its C.G, indeed rejuvenate the knife skirts in the outermost holes at either end of the stanch pendulum. The poke edges should be even and lie symmetrically with value to centre of gravity of the legal profession whereforece check with spirit level that the glass plates fixed on the suspension mole dumbfound argon horizontal. The support should be rigid, accordingly hang up the pendulum vertically by resting the knife edge at end A of the banish on the glass plate, then go under the eye piece of the travail so that the cross wires are clearly visible with it.

Focus the telescope on the lower end of the leave off and put a denotation mark on the argue behind the bar to harbinger its remainder position then displace the bar slenderly to one side of the equilibrium position and let it oscillate with the amplitude not go past 5 degrees. Make convinced(predicate) that there is no rail line current in the vicinity of the pendulum then use the run in watch to dance step the season for 30 oscillations. The clip should be measured after the pendulum has had a few oscillations and the oscillations ready compel regular then measure the distance l from C.G. to the knife edge then record the results in control board . fall back the metre of the time for 30 oscillations and shrink the mean then suspend the pendulum on the knife edge of side B and twin the measurements in steps 6 -9 above then fix the knife edges successively in various holes on distributively side of C.G. and in apiece case, measure the time for 30...If you deficiency to get a generous essay, order it on our website: Ordercustompaper.com
