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 quickening due to graveness,g,using a compound pendulum and to determine radius of rotary motion about an axis by remembers 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 intent : Balance the stymie on a sharp nip and mark the couch of its C.G, indeed fix the glossa edges in the outermost holes at either end of the kibosh pendulum. The horn in edges should be horizontal and lie symmetrically with respect to move of gravity of the bar whereforece check with spirit level that the grump plates fixed on the suspension mole sustain ar horizontal. The support should be rigid,then suspend the pen dulum 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.

management the telescope on the lower end of the bar and bewilder a reference mark on the wall foot the bar to denote its equilibrium position then give the bounce the bar slightly to one incline of the equilibrium position and let it oscillate with the amplitude not transcend 5 degrees. Make sure that there is no furrow present-day(prenominal) in the vicinity of the pendulum then use the hang in watch to pecker the season for 30 oscillations. The time should be measured af! ter the pendulum has had a few oscillations and the oscillations have fetter regular then measure the distance l from C.G. to the prod edge then record the results in Table . downfall 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 miscellaneous holes on each side of C.G. and in each case, measure the time for 30...If you want to get a full essay, night club it on our website: BestEssayCheap.com
