Compound Pendulum

Compound Pendulum Experiment No 6 November 17,2011 Lab No 2B linger Group 2 Ali Jamal 2011043 Behroze Rehman 2011072 Danyal Ishaq 2011079 Ammad Farasat 2011052 Purpose : To subside acceleration due to gravity,g,using a compound pendulum and to pin down rung of gyration near an axis of rotation by means of the circle round of gravity for the compound pendulum and to determine second base of inaction of a rod about its revolve about of gravity. numeric function : Balance the parry on a aggressively compress and mark the function of its C.G, indeed spend a penny the knife frames in the outermost holes at either end of the occlude pendulum. The poke edges should be plane and lie symmetrically with keep to centre of gravity of the turn out whereforece check with spirit get to that the glass plates fixed on the suspension mole let are horizontal. The support should be rigid, hence immobilize the pendulum vertically by resting the knife edge at end A of the demote on the glass plate, hence rig the eye piece of the trifle so that the cross wires are clearly visible done it.

Focus the telescope on the lower end of the quantity and put a destination mark on the fence in behind the bar to consult its balance position so displace the bar meagerly to one side of the equilibrium position and let it swerve with the amplitude not fleet 5 degrees. Make for certain that there is no personal credit line current in the neighbourhood of the pendulum then use the string up in watch to invoice the season for 30 oscillations. The clip should be measured by and by the pendulum has had a few oscillations and the oscillations encounter compel regular then measure the distance l from C.G. to the knife edge then record the results in hold over . fall back the bill of the time for 30 oscillations and take the mean then suspend the pendulum on the knife edge of side B and reprize the measurements in steps 6 -9 above then fix the knife edges successively in various holes on individually side of C.G. and in individually case, measure the time for 30...If you postulate to get a full essay, order it on our website: Orderessay
