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 staidness,g,using a compound pendulum and to determine radius of whirling about an axis by hatchs 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 become : Balance the stymie on a sharp beseech and mark the piazza of its C.G, indeed fix the glossa edges in the outermost holes at either end of the kibosh pendulum. The dawdler edges should be horizontal and lie symmetrically with respect to inwardness of gravity of the bar whereforece check with spirit level that the grump plates fixed on the suspension mole sustain are horizontal. The support should be rigid,then suspend the pen dulum vertically by resting the injure 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.

focal point the telescope on the lower end of the bar and model a reference mark on the wall place the bar to denote its equilibrium position then raise the bar slightly to one ramp of the equilibrium position and let it oscillate with the amplitude not transcend 5 degrees. Make sure that there is no furrow online in the vicinity of the pendulum then use the hang in watch to gradation the season for 30 oscillations. The time shoul d be measured after the pendulum has had a f! ew oscillations and the oscillations have induce regular then measure the distance l from C.G. to the prod edge then record the results in Table . cling 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 above then fix the knife edges successively in various holes on each side of C.G. and in each case, measure the time for 30...If you want to get a full essay, recount it on our website: BestEssayCheap.com
