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 acceleration due to gravity,g,using a compound pendulum and to determine radius of revolution about an axis by opines 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 give-up the ghost : Balance the stymie on a sharp press out and mark the blank space of its C.G, indeed fix the glossa edges in the outermost holes at either end of the kibosh pendulum. The liberation edges should be horizontal and lie symmetrically with respect to means of gravity of the bar whereforece check with spirit level that the internal-combustion engine plates fixed on the suspension mole sustain be horizontal. The suppor t should be rigid,then suspend the pendulum vertically by resting the stab 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. focus the telescope on the lower end of the bar and frame up a reference mark on the wall derriere the bar to denote its equilibrium position then dissolve the bar slightly to one face of the equilibrium position and let it oscillate with the amplitude not transcend 5 degrees. Make sure that there is no furrow underway in the vicinity of the pendulum then use the hang in watch to greenback the season for 30 oscillations. The time should be measured after the pendulum has had a few oscillations and the oscillations have hold regular then measure the distance l from C.G. to the tongue edge then record the results in Table . nightfall 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 su! pra then fix the knife edges successively in variant holes on each side of C.G. and in each case, measure the time for 30...If you want to get a full essay, vow it on our website: BestEssayCheap.com
