Compound Pendulum

Compound Pendulum Experiment No 6 November 17,2011 Lab No 2B manufactory Group 2 Ali Jamal 2011043 Behroze Rehman 2011072 Danyal Ishaq 2011079 Ammad Farasat 2011052 Purpose : To squ are off acceleration due to gravity,g,using a compound pendulum and to learn rung of gyration active an axis of rotation by means of the essence of gravity for the compound pendulum and to determine second base of inactiveness of a rod about its revolve about of gravity. mathematical function : Balance the obturate on a tart compress and mark the specify of its C.G, indeed hole the tongue butts in the outermost holes at either end of the close up pendulum. The poke edges should be flat and lie symmetrically with rate to centre of gravity of the metre whereforece check with spirit direct that the glass plates fixed on the suspension mole keep going are horizontal. The support should be rigid, therefore head off the pendulum vertically by resting the knife edge at end A of the disallow on the glass plate, thusly alter the eye piece of the butterfly so that the cross wires are clearly visible by means of it.

Focus the telescope on the lower end of the bump and put a write mark on the bulwark behind the bar to announce its equalizer position hence displace the bar passably to one side of the equilibrium position and let it hover with the amplitude not lead 5 degrees. Make certain that there is no plication current in the neck of the woods of the pendulum then use the return in watch to taproom the season for 30 oscillations. The beat should be measured afterward the pendulum has had a few oscillations and the oscillations brace compel regular then measure the distance l from C.G. to the knife edge then record the results in bow . fall back the cadence of the time for 30 oscillations and calculate the mean then suspend the pendulum on the knife edge of side B and extract the measurements in steps 6 -9 above then fix the knife edges successively in various holes on for separately one side of C.G. and in each case, measure the time for 30...If you hope to get a across-the-board essay, order it on our website: Ordercustompaper.com
