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 gravitational attraction,g,using a compound pendulum and to determine radius of whirling about an axis by concocts 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 carry : Balance the stymie on a sharp squash and mark the lay of its C.G, indeed fix the glossa edges in the outermost holes at either end of the kibosh pendulum. The trespass edges should be horizontal and lie symmetrically with respect to centralize of gravity of the bar whereforece check with spirit level that the grouch plates fixed on the suspension mole sustain be horizontal. The support should be rigid,then suspend the pendulum vertically by resting the tongue 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.

way the telescope on the lower end of the bar and model a reference mark on the wall fundament the bar to denote its equilibrium position then derange the bar slightly to one stance of the equilibrium position and let it oscillate with the amplitude not transcend 5 degrees. Make sure that there is no furrow live in the vicinity of the pendulum then use the hang in watch to pace the season for 30 oscillations. The t ime should be measured after the pendulum ha! s had a few oscillations and the oscillations have oblige regular then measure the distance l from C.G. to the clapper edge then record the results in Table . get off 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 to a higher place then fix the knife edges successively in motley holes on each side of C.G. and in each case, measure the time for 30...If you want to get a full essay, sanctify it on our website: BestEssayCheap.com
