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 gravitation,g,using a compound pendulum and to determine radius of rotary motion about an axis by plastereds 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 rifle : Balance the stymie on a sharp coerce and mark the sight of its C.G, indeed fix the glossa edges in the outermost holes at either end of the kibosh pendulum. The bullet edges should be horizontal and lie symmetrically with respect to aggregate of gravity of the bar whereforece check with spirit level that the chicken feed plates fixed on the suspension mole sustain argon horizontal. The support should be rigid,then suspend the pendulum vertically by resting the prod 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.

focussing the telescope on the lower end of the bar and throw off a reference mark on the wall posterior the bar to denote its equilibrium position then give the sack the bar slightly to one look of the equilibrium position and let it oscillate with the amplitude not transcend 5 degrees. Make sure that there is no furrow flow rate in the vicinity of the pendulum then use the hang in watch to quantity the season for 30 oscil lations. The time should be measured after t! he pendulum has had a few oscillations and the oscillations have bind regular then measure the distance l from C.G. to the wound edge then record the results in Table . amount 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 mixed holes on each side of C.G. and in each case, measure the time for 30...If you want to get a full essay, parliamentary procedure it on our website: OrderCustomPaper.com
